Select Ponds of America — Koi Pond Filtration Specialists
World-class gravity filtration systems. Collector-grade environments. Built in collaboration with architects, engineers, and general contractors across America and beyond.
Select Ponds of America is led by Hunter Nieman — a Shinkokai-certified koi judge, Japan-sourced koi specialist, and gravity filtration expert with a track record that spans the most demanding collectors in the world.
We are not general contractors. We are specialists. We work alongside your architects, engineers, and GCs to deliver pond environments that perform flawlessly for generations.
As the official Filtreau Ambassador for the United States, we bring the finest European filtration technology directly to American projects — combined with hands-on expertise no catalog can replicate.
From private estates to landmark public installations — if it holds koi, it deserves to be built right.
We design and install gravity-fed filtration systems that deliver optimal water quality, biological balance, and long-term fish health — engineered for each unique environment using Filtreau's industry-leading technology.
We work with your architect, engineer, or general contractor from the earliest design phase. Our expertise ensures every structural and filtration decision supports the long-term health of your koi environment.
Professional concrete pond builds with natural stone edging, elegant forms, and LED water movement. Every pond we build is designed to become a permanent landmark on your property.
Ongoing service agreements for discerning collectors who demand consistent, expert attention to their investment. We maintain the environments we build — and others we haven't.
As Filtreau's US Ambassador, we supply premium European gravity filtration components to qualified installers and builders nationwide. The finest systems, sourced direct.
Complex, large-scale, or public koi installations require a specialist embedded in the design process. We bring the technical knowledge your team needs — without replacing the professionals already on your project.
