We keep water clear and your koi thriving with expert seasonal pond maintenance.
At Domain Aquascapes, we know a koi pond is more than a water feature. It is a living system that needs the right care to keep your fish healthy, your water clear, and your pond looking its best all year. Our koi pond care service is built for homeowners who want peace of mind, better water quality, and expert help from a team that understands pond ecosystems, filtration, fish health, and seasonal maintenance.
We provide hands-on koi pond maintenance for ponds of many sizes and styles. Whether your pond needs routine upkeep, a seasonal service visit, or help solving water quality problems, we can step in with practical solutions. Our goal is simple: protect your koi, support a balanced pond environment, and help you enjoy your pond without the stress of managing every detail on your own.
Our service can be tailored to the needs of your pond, fish load, equipment, and time of year. Typical koi pond care may include:
Every koi pond is different. Some ponds need light routine maintenance. Others need deeper cleaning, equipment attention, and closer monitoring to stay balanced. We assess what your pond needs and create a service plan that makes sense for your setup.
Koi are valuable fish, and they depend on stable water conditions to thrive. Poor filtration, excess debris, overfeeding, algae growth, and neglected equipment can all lead to stress for your fish and problems in the pond. Regular koi pond maintenance helps reduce these risks before they turn into larger and more expensive issues.
Professional pond care can help with:
When a koi pond is properly maintained, the whole system works better. Water moves the way it should, filters do their job, and fish have a healthier environment. That means fewer surprises and more time enjoying your pond.
Seasonal care is one of the most important parts of keeping a koi pond in good condition. Weather changes affect water temperature, fish activity, debris levels, and biological balance. We offer seasonal pond maintenance to help your system adjust throughout the year.
Spring is the time to wake the pond back up after winter. This may include clearing out settled debris, checking pumps and filtration, inspecting water movement, and getting the pond ready for warmer weather and increased fish activity. Spring service helps set the stage for a healthy season.
In summer, koi ponds often deal with warmer water, faster algae growth, and heavier biological demand. We focus on keeping filtration working well, maintaining circulation and aeration, and watching for issues that can affect fish health during hot weather.
Falling leaves and cooling temperatures can create extra waste and put stress on the pond system. Fall maintenance helps remove debris, protect equipment, and prepare the pond for the colder months ahead.
Winter pond needs vary based on the setup and local conditions. We can help you understand what should stay running, what should be monitored, and how to support your koi through cold-weather conditions with less risk to the pond system.
Many customers call us when something seems off with the pond, even if they are not sure what caused it. We can help identify maintenance-related issues such as:
In many cases, these problems are connected. A dirty filter can reduce flow. Poor flow can affect oxygen levels. Extra waste can impact water quality. That is why we look at the full pond system instead of treating just one symptom.
We take a careful, practical approach to koi pond care. We do not rush through the job or use a one-size-fits-all method. We pay attention to how your pond is built, how many fish it holds, what equipment it uses, and how the water is behaving. That lets us make smarter maintenance decisions that support both the beauty of the pond and the health of the koi.
As a hands-on aquascapes company, we understand that pond care is about more than cleaning. It is about protecting a balanced ecosystem. Healthy koi ponds depend on circulation, filtration, oxygen, and responsible maintenance over time. We help homeowners stay ahead of issues so the pond stays more stable and easier to manage.
Our koi pond care service is a great fit for homeowners who:
Whether your pond is newer or well established, regular maintenance can make a big difference in appearance, equipment life, and fish health.
We bring real-world experience, attention to detail, and a strong understanding of koi pond systems. Our customers trust us because we show up ready to help, explain what we see in clear terms, and focus on the long-term health of the pond. We believe good service should be honest, thorough, and useful.
If your koi pond needs routine maintenance, seasonal care, or help getting back on track, we are ready to help. Call Domain Aquascapes at (206) 607-7509 to schedule koi pond care or talk with us about what your pond needs.
When you call Domain Aquascapes at (206) 607-7509, we start with a full koi pond assessment, including water clarity, fish behavior, filtration, aeration, and seasonal concerns. We identify stress points early and explain exactly what your pond needs before any maintenance begins.
Next, we schedule service at the right time for your pond and build a care plan around feeding, beneficial bacteria, debris load, algae pressure, and equipment performance. This step helps us protect your koi, stabilize water quality, and prevent bigger pond repairs later.
We complete the pond maintenance with careful cleaning, filter service, water treatments, and a final health check to make sure your koi and ecosystem are thriving. Before we leave, we review what we did, share simple next-step advice, and recommend ongoing maintenance if needed.
Common questions we hear from homeowners who want clean water, healthy koi, and less stress. If you do not see your question here, call Domain Aquascapes at (206) 607-7509 and we will be happy to help.
Our koi pond care service is built to keep your fish healthy and your pond looking its best. We handle seasonal pond maintenance, debris removal, filter cleaning, water quality checks, algae control, pump and skimmer inspection, and general pond cleaning. We also keep an eye on fish behavior and overall pond health so small issues do not turn into expensive repairs.
Most koi ponds need regular care throughout the year. The exact schedule depends on pond size, fish load, trees nearby, filtration, and how clear you want the water to stay. Many of our customers do best with routine service during the active season, plus key spring start-up and fall cleanout visits. We can recommend a plan that fits your pond and your budget.
No. We clean ponds with fish safety in mind. We use careful methods to reduce stress on your koi while improving water quality and pond conditions. With years of hands-on aquascape and pond maintenance experience, we know how to clean the pond, service the equipment, and protect the balance your fish need.
Yes. Green water, cloudy water, string algae, and bad odor are some of the most common problems we solve. These issues usually come from a mix of sunlight, nutrients, filtration problems, sludge buildup, or overdue maintenance. We inspect the whole pond system, find the cause, and recommend the right fix so you get clearer water and a healthier pond.
We offer both. Some homeowners call us for a one-time pond cleaning or seasonal visit. Others want scheduled koi pond maintenance so they do not have to worry about filters, water quality, and fish care. We are happy to provide ongoing service and help you stay ahead of pond problems before they get worse.
If your fish seem stressed, the water stays murky, algae keeps coming back, the pump is not working right, or the pond has a heavy sludge buildup, it is time to call. Professional care can save you time, protect your koi, and help prevent bigger repair costs later. If you want honest advice and reliable service, call Domain Aquascapes at (206) 607-7509 to schedule your koi pond care.
Real feedback on clear water, healthy koi, and dependable pond care that lasts
"Incredible Water Feature Installation! I am part of an HOA community in Herndon, VA. We were looking to upgrade our existing water fountain to a new water feature that was beautiful but also lower maintenance. Ryan came up with the idea of stacked slate water urns with a large aquablox underground water reservoir to support the water feature. Through the project Ryan and his team demonstrated professionalism, patience, excellent communication, knowledge, punctuality and pride in their completed work. I would highly recommend Domain Aquascapes to anyone/organization looking for a water feature. We look forward to working with Domain Aquascapes moving forward with a maintenance contract to keep our gorgeous water feature beautiful for the community moving forward. Thank you Domain Aquascapes!"
"Fantastic rebuild of my 21 year old pond. Ryan and his team were professional, hardworking, talented and super informative. My pond has never looked better."
"Last year I moved into a house with a neglected Koi pond. Ryan and his crew at Domain came in and completely saved the day.Their knowledge of their craft, and attention to detail is the kind of pedigree you want in a contractor who is installing these type of ecosystems…and all at a very fair price. I highly recommend Ryan and Domain Aquascapes for any/all of your outdoor living water feature systems…and I look forward to working with Ryan at several of my properties in the future."
"Ryan and his team came out to clean up and landscape my very overgrown front and back yard. They were very responsive and came out to give us a quote quickly. They were professional and did a really incredible job. We are already planning to have them back in the spring!"
"Very pleased! Walked us through every stage of the project and executed flawlessly!"
"I contacted Ryan for a pump replacement in my outdoor fountain. My job was a little too small for his business but he sent me the link to the pump I needed and gave me instructions to complete the replacement. Ryan is a honest and kind businessman, I'm thankful for his help!"
"Hired Ryan and Heather at Domain Aquascapes for the design and build of our front yard landscaping. They were great to work with on the overall design and on determining our specific plant and stone preferences. They are very knowledgeable and helped us select native plants that look great and that are environmentally responsible. The work was done very well; nothing was rushed or done carelessly. Whenever there was any uncertainty about anything, they came to us for clarification. They made sure we were completely satisfied with the result before leaving the job. Although we did not end up choosing to install a water feature, I have no doubt that it would also have been excellent quality if we had. We will be calling them first for our future landscaping projects."
"Ryan and Heather are simply the most amazing people. I came to them with a very ambiguous and undefined want to make a memory pond for my deceased mom. Ryan’s eye, vision, emotional intelligence, and finally the unparalleled execution of the request created a space I could not have dreamt of. He took a new not very large patio deck, reshaped it, and not only created a showpiece that surprises all that see it, he actually made the space “bigger,” more lively, and more actively used. I cannot give Domain a higher recommendation. If you are thinking of a project of ANY size, Ryan is your go to. Period, end of sentence."
"Made a beautiful lighted walkway for my parents house. They were a dynamic duo. Very punctual and friendly and am comfortable using them in the future. I am going to use them for my Christmas lights so I’m excited!"
"Ryan came out promptly and repaired my leaking pond. Highly recommend!"
"Ryan and Heather were wonderful to work with. They were highly responsive and communicated clearly throughout the whole process. I am a new homeowner with a lot of big trees on my property. In addition to tree trimming service, they provided helpful suggestions about future ideas, but were absolutely not pushy or trying to upsell anything. They did great work, and they did it quite quickly. I highly recommend and would use them again for trees and other services they offer."
"It was past time to give our front flowerbed some attention. When we saw the work done in our neighbor's backyard, we contacted the same company, Domain Aquascapes. Ryan and Heather were quick to respond and super friendly. Ryan came out to take a look at our sad situation and talked with us to get an idea of our preferences (low / no maintenance, good drainage, curb appeal). They worked efficiently, kept us updated on the progress and changes, and were reasonably priced. We love our new rock garden!"
"Exceptional customer service! Had called to get small fountain cleaned and reconnected. Ryan came by the next day and did an excellent job at a reasonable rate. When the fountain emptied out sooner than expected, Ryan and Jackson came back and sealed any possible leaks. They spent a considerable amount of time making sure that the fountain was working just right. Would most definitely recommend Domain Aquascapes."
"Domain Aquascapes helped me with a drainage issue with my sump pump. Ryan and his team worked diligently to identify the problem and then came up with a solution same-day. He was honest and his pricing was reasonable. I’d absolutely recommend Ryan for drainage needs."
"They did an amazing job on my patio! Very efficient and detailed. I highly recommend hiring them for your landscaping/weeding. I will definitely be calling them back myself for any upkeep."
"I needed a sixty foot tall Tulip Poplar with a diseased crown removed, several limbs on other trees pruned to raise the canopy and a large horizontal oak limb cabled. Ryan Compton led the team and earned 5 stars The crew was especially careful closing gates to keep my dogs safe Ryan completed the work timely and charged fairly. He was careful to use top quality materials to cable the Oak limb. The previous cable had snapped due to rust and metal fatigue It was a pleasure doing business with Domain Aquascapes. They also went the extra mile to make sure that I would not have a future problem with the trees near my fencing I highly recommend them to anyone requiring professional tree services."
"Ryan and his partner were able to repair a wall mounted spillover fountain on my patio that the installation company was unable to fix. He and his partner were very courteous, responsive, and professional. They went above and beyond to make sure I understood future maintenance to make sure the fountain continues to operate correctly. Highly recommend!"
"Ryan was super friendly and knowledgeable when it came to designing a pond. Other companies put 3x the price and couldn’t answer all of my questions so I wasn’t sure they were providing the exact service I was looking for. If you’re looking for someone professional, honest and prioritizes customer service. Ryan is your guy! Highly recommend."
"I have hired Ryan and Heather for my landscape work. They were very reasonable, responsive, and polite. The work they have done is impeccable and detailed. Most of the other contractors asked for 50% upfront before even show up. These guys trusted us and completed every detail of the work before the payment. I will use them for any other landscaping work in the future."
"Very rare when you find a someone who has so much passion and competency in what they do ... Ryan and his crew surpassed all expectations. Ryan design and vision of the project was right on target creating a peaceful oasis in my backyard. Scheduling and communication was always prompt and clear. Costs was very reasonable and clearly understood. No need to look any further for the best pond company in the area."
"Would strongly recommend Domain. For initial estimate for tree removal, Ryan promptly came out and provided a competitive estimate, but what distinguished his bid was his explanation of what and why he would do (or not do) certain things. Further communications were prompt and clear. Very happy with the work and will use again when needed!"
"Ryan and his team did such an amazing job on our pond and waterfalls! When he came out to describe what he could do it sounded nice, but after it was fully installed it surpassed our expectations by a mile! The vision that he had and what he delivered is absolutely incredible! He truly understands and knows how to replicate Mother Nature and blend the water feature into the landscape. It looks so amazing with the aquatic plants and the underwater lighting in the evening is absolutely stunning! Now that the pond is the new hang out, we are seriously considering koi fish. We will be calling him very soon to get us set up for that. Truly an artist!"
"Ryan helped us in a dire pond crisis, he came out the same day on a weekend to fix a leak, which would have ultimately taken away our Koi that we have raised for many years. He was very kind, patient, and knowledgeable and he will have my business for many years to come. Thank-You Ryan :)"
"Domain Aquascapes are my dream pool and garden team. They check the boxes above for good quality, good value, professional, responsive and on time. More than that they were working on my pond on the hottest day of the year and were great about hydrating and not overheating. Ryan recognized some of my garden problems and suggested solutions which he and Heather implemented. They were prompt about returning to finish my pond. They also were able to do a spur of the moment project on their busy weekend. I can't wait to use them again. Ten stars!"
"Ryan and his partner fixed my urn fountain, which had lost pressure and was not flowing well. They found the source of the problem, fixed it, and provided some tips about how to care for the fountain. They also made some changes to help the fountain work more smoothly in the future. What I appreciated most about Ryan and Domain Aquascapes was how responsive they were and how quickly they came out to fix my issue - a total of just a few days from first email to solving the issue. Highly recommended!"
"We contracted Ryan for doing a landscape work around our home. He did an excellent job including preparing the area, bringing the approved materials, stones etc . We are happy how it turned out. The job was completed on time and I will recommend his services anytime!"
"Our homeowner's association in Reston hired Ryan and Heather to clean up the silt, leaves, and algae that had settled on the bottom of the coves around our three ponds and their associated water features. They also removed overgrown grasses and trimmed bushes around the perimeter of the ponds. They did a beautiful job! They were easy to work with and never shy with sharing ideas on how to improve the appearance of the areas in which they worked. Ryan is very particular about his work and has high standards for his performance. We hope to have them back to continue the excellent work they have done for us. Our residents are delighted!"
"Ryan did such a fantastic job with the landscaping that we requested. He was great with communication, on time, efficient, very easy to work with, made sure to check up on any adjustments, and was extremely well priced. Our house has had a lot of work, and Ryan is by far the most excellent person we have worked with, and I will definitely be calling him again for future work. I cannot recommend him more highly and will be spreading the word to friends and neighbors!"
"Ryan and his team did an amazing job on my pond. They were professional, showed up when they said they would, immediately fixed the one issue that came up afterwards, and I will highly recommend them to all of my friends, neighbors, and real estate clients. It's a great company and they do wonderful work. My pond is gorgeous!"
"I was referred to Ryan and Heather by my neighbors. I shared a few Pinterest photos with ideas, and they were able to turn around design options within a matter of days! They took great care in walking me through the entire build process. I love my new front yard and get compliments from strangers walking past my home nearly every day. My only regret is that I didn’t work with Ryan and Heather sooner. I look forward to working with them on future landscaping projects!"
"Very experienced and knowledgeable."
"Wonderful experience start to finish with Ryan and Heather! We had a small sloped area in the back yard, and they made the vision come true for an amazing waterfall. They were so easy to work with and had great ideas, and were very interested in my input as well. The waterfall truly looks like it just emerged from the hill intact, as though nature had put it there, and their lighting ideas make it enjoyable at night too. We went together to pick out the landscaping when the waterfall was done, which just elevated the whole thing to another level of beauty. Wholeheartedly recommend them if you are considering a water feature!"
"I highly recommend recommend Ryan. He thoroughly cleaned our pond and spent a significant amount of time with me explaining details about the pond and plants. He communicated with me before during and after. We plan to use him to expand our pond to Incorporate koi. He and Chris were very personable. If you want a pond done right the first time this is the company to call"
"Ryan came and cleaned our our two-tier pond with waterfall and set up our fountain pumps. He also recommended a great pump for our waterfall feature that makes our pond the spectacle of the back yard! He also helped us troubleshoot some broken exterior lighting, which we couldn’t have done without his expertise! I got quotes from 5 companies and am so glad we chose to go with Domain Aquascapes. We will be using his service from here on out!!"
"Ryan and Heather designed and built a garden pond for me this past week and it is beautiful beyond what I imagined! They used rocks I already had in my yard and built a two level pond with a small waterfall. It was completed in one day and the result is a beautiful natural area that will attract wildlife and serve as a focal point for my patio. I have also had them do tree pruning on most of my trees. They did the best job over any other company I have ever had. And their prices are extremely reasonable. I heartily recommend them for all your needs."
"Ryan and his team do amazing work and are incredibly customer focused. The creative aspects of Aquascapes taking a high degree of ingenuity, creativity, and innovation. I highly recommend using Domain Aquascapes!!"
"We found Ryan through his ad on Craigslist and are so happy we did! He and his partner did a fantastic job on our yard - trimming hedges, weeding, mulch, edging and treating some bushes that needed some TLC. He is very knowledgeable and meticulous about his work and he went above and beyond to make our yard look great for a very reasonable price. Our neighbor hired him too after seeing him at our house so I witnessed that great work as well. He and his partner worked continuously until everything was completed to perfection. Highly recommend them for any landscaping needs!"
"Ryan was really knowledgeable and patient. They cleaned out our fountain and replaced the pump. Actually they set it up so it’s easier to maintain in the future. Now our fountain is running better than when it was first installed!"

"We have had a koi pond for 20+ years. In 2023, we had a new waterfall, skimmer and a bunch of lights installed. The lights stopped working. Unfortunately, the folks who installed everything have since retired and the new folks don't service ponds, and don't have the records of their predecessor. We called Ryan at Domain Aquascapes, and he went the extra yard to determine what kind of lights we had, confirmed they are still under warranty based on the codes/markings on the lights. And informed us they are 100% exchangeable for working lights. Thank you Ryan, We have 6 lights that are out, and at $160/per light, this is saving us a bundle. Thanks again!"
"Ryan was so responsive when I discovered a water issue in my basement. He helped quickly assess and resolve the problem. Highly recommend."
"Ryan and his team went above and beyond.I can't believe how nice it turned out. They were so Friendly and professional. These guys really know their stuff.I will definitely recommend them.Five stars for me"
"Ryan is truly a Pond Whisperer. We were at wits' end with our water feature, having tried several contractors who either suggested a rebuild for $20K or just shrugged their shoulders and said good luck. Ryan came in, looked around, visualized the system as it could be, and in short order found the problems, corrected them, and reassembled the whole thing holding water and looking better than it ever had since we bought the house. He has a combination of knowledge, intuition, and passion for his work. I strongly recommend him for anything related to water features, whether it's designing and building them or servicing existing ones."
"First rate landscapers. Ryan and Heather were responsive, flexible, experienced and professional. From first consultation to estimate to design to construction of a lovely little stream, waterfall, & pond in our backyard. The birds love it. We do too. Highly recommended."

"Outdoor Christmas Lighting - Ryan and Heather did an outstanding job on our home and lawn. We messaged them on a Friday and they were at the house on Saturday for the estimate, started on Monday and finished on Tuesday. Gave us options for using theirs or our lights and we did a combination. We have always wanted to frame the two story roof and dormers with lights and it looks great. The C9 LED lights were custom measured and installed with no leftover lights. We also opted to light up 12 steeplechase arbor vitae trees with clear net lights and our azaleas with multi-colored lights. Meticulous, neat, professional, and very easy to work with, we highly recommend them for any holiday lighting needs. We have received many compliments on our busy street."
