Concrete Koi Ponds · Gravity Filtration · Living Art
Custom concrete koi ponds and gravity filtration, created as living art for the world’s most serious koi collectors — across America and beyond.
Select Ponds of America is led by Hunter Nieman — an artist first, a Shinkokai-certified koi judge, and a gravity filtration specialist whose concrete koi ponds are home to some of the finest koi collections in the world.
We are not contractors. Every pond is an original creation, and we personally choose each project to make sure it is the right fit for our work. We collaborate with your architects, engineers, and builders so that every structural and filtration decision serves the koi — for generations.
Our signature work includes six koi ponds created for renowned collector Herbert Fritch: three inside a 10,000 sq ft greenhouse and three more inside a 6,500 sq ft greenhouse. These projects were featured in videos published by The Koi Partner on YouTube.
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.
Custom concrete koi ponds with bottom drains, natural stone edging, elegant forms, and LED water movement — engineered around gravity filtration from day one. 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.

The Zen Nippon Nishikigoi Shinkokai — the All Japan Nishikigoi Promotion Association — is Japan’s association of professional koi breeders and dealers, based in Niigata, the birthplace of nishikigoi. It organizes the All Japan Koi Show in Tokyo, the event that decides the world’s top koi each year.
Hunter Nieman was honored to be invited to join by the breeders themselves. He sees it less as a title and more as a responsibility: to respect the koi, the families who devote their lives to raising them, and the traditions of Niigata — and to keep learning from them.
For our clients, it means every koi we recommend and every pond we create is approached with the care and respect for the fish that we have learned from Japan’s breeders.
Koi purchased through Select Ponds of America are sourced from our partner dealers in Japan and are subject to import costs and tariffs. Import laws and regulations are subject to change.
Koi prices include shipping to the USA but do not include domestic shipping charges.
