Built for koi health
Correct depth, aeration, and filtration keep koi thriving through hot summers.
A WETYR koi pond is a balanced ecosystem, not a kit. We build naturalistic ponds where rock, plants, fish, and filtration work together for clear water and healthy koi.
Ecosystem ponds stay clear and healthy because every element supports the others. Proper depth, aeration, biological filtration, rock, and aquatic plants create a self-balancing habitat that needs less effort and looks better every year. We design koi ponds with the right shade and depth for the climate, often paired with a waterfall or stream.
WETYR Pools handles koi ponds as a craftsman-led, design-build team. The people who plan your project are the people who build it and stand behind it, with no quality lost in the handoffs between separate companies. One team, one standard, and one point of accountability from the first conversation through long-term care.
A swimming pool is something you use. A koi pond is something you live alongside. The people who own a well-built koi pond describe it the way they describe a garden they love or a pet they are fond of, not the way they describe an appliance. The fish learn your routine and rise to greet you. The water changes character through the day and the seasons. It becomes the place a morning coffee gets longer and an evening winds down. That is the real reason to build one.
It is also why the difference between a real pond and a kit pond matters so much. A kit pond, a liner, a small pump, and a bucket of optimism, photographs acceptably for one season and then turns into a green, struggling chore. The fish do poorly, the water never clears, and the feature becomes a source of guilt rather than pleasure. A genuine ecosystem pond does the opposite. It gets clearer, healthier, and more beautiful every year, and it asks remarkably little in return.
WETYR Pools builds koi ponds as true living ecosystems, engineered around the long, healthy life of the fish. Every element, the depth, the rock, the plants, the filtration, the aeration, is there to support the others, so the pond balances itself. The goal is a pond you enjoy for decades, not one you fight for a summer.
Correct depth, aeration, and filtration keep koi thriving through hot summers.
Hand-placed stone and aquatic planting make the pond look like nature put it there.
A balanced ecosystem keeps water clear with far less maintenance than a kit pond.
Add moving water for sound, oxygenation, and beauty.
Clear water and healthy koi are not the result of constant effort. They are the result of a system where every element does a job. Build the system correctly and it runs itself; leave a piece out and it never quite works.
Koi grow large and live for decades, and they need real depth and volume to stay healthy. Adequate depth protects them from predators and from temperature swings, and gives the whole pond the stable mass it needs to hold its balance.
Stone and gravel are not just decoration. They line the pond, host the vast colonies of beneficial bacteria that process waste, and give the system enormous biological surface area. Hand-placed rock also makes the pond look like nature built it.
A skimmer captures debris before it sinks, a biological filter gives bacteria a home, and a waterfall or aerator keeps oxygen high. Together they break the cycle that feeds algae and keep the water healthy for fish around the clock.
Water lilies shade the surface and starve algae of light, while marginal plants pull dissolved nutrients straight out of the water. Plants are the working filter that, with the bacteria, keeps a balanced pond clear.
Koi are hardy, adaptable fish, but a hot climate places real demands on a pond, and those demands have to be designed for rather than discovered. Warm water holds less dissolved oxygen, summer heat accelerates algae and bioload, and shallow water can swing in temperature in a way that stresses fish. A pond that ignores these realities will struggle every summer; a pond that anticipates them will not.
WETYR Pools designs koi ponds with the climate built into every decision. We build in enough depth to give the fish a cool, stable refuge. We size aeration and filtration generously, with headroom for the warmest part of the year, because the warm nights of summer are exactly when oxygen demand peaks. We use planting and placement to provide shade, and we keep the water moving with waterfalls and streams that oxygenate as they circulate.
The payoff is fish that stay healthy and a pond that stays clear right through the hottest months, when poorly built ponds turn green and lose fish. A koi pond is a long-term commitment, and we design it so that commitment is rewarded year after year.
Every WETYR pond begins with how you want to experience it. Where will you see it from inside the house? Where will you sit beside it? Do you want the gentle, constant sound of a waterfall, or a quiet, still surface? How many koi do you imagine, and do you want a viewing depth where you can really watch them? Those answers shape the size, the depth, the routing of streams, and the placement of rock and planting.
One of our favorite designs pairs a koi pond with a swimming pool. Designed together, the two share stonework, planting, and a single landscape language, so you swim in clean, balanced pool water while a living pond and a cascade sit just beyond. It is the best of both: the recreation of a pool and the calm, living beauty of a pond, in one cohesive backyard that feels like a private retreat.
Whatever the scope, you receive a fixed, itemized proposal before work begins, and our own crews carry the project from excavation through rock placement, planting, and the careful introduction of fish. And because we also offer pond maintenance, the same team can keep the ecosystem in balance long after it is built.
Clear answers to the questions homeowners ask most.
A properly built ecosystem pond is low effort, because the plants, rock, bacteria, and filtration keep it balanced on their own. The ponds that become a chore are undersized kits with no real biology. We also offer pond maintenance plans for fully hands-off care.
Yes, when the pond is built for it. Adequate depth gives fish a cool, stable refuge, and generously sized aeration and filtration handle the lower oxygen and higher bioload of warm water. We design ponds specifically for their climate so koi stay healthy.
Yes, and it is one of our most popular designs. Built together, a koi pond and a swimming pool share stonework and planting and read as one landscape, giving you the recreation of a pool and the living calm of a pond in a single backyard.
Koi need real depth to stay healthy, to be protected from predators and temperature swings, and to give the pond stable volume. The right depth depends on the design and the climate, and we engineer it specifically for a long, healthy life for the fish.
Kit ponds usually lack the depth, the filtration, the aeration, and the planting balance that a real ecosystem needs. Without those, nutrients build up, algae takes over, and the fish struggle. A properly engineered ecosystem pond avoids this by design.
Fish are introduced last, only once the pond has been filled, planted, and given time for the system to begin establishing. Adding koi to a pond that is already alive and balanced gives them the healthiest possible start.
