Koi Pond Systems & Pond Filters

Improve Water Clarity and Create a Thriving Environment for Your Koi Pond or Water Garden

Our filters are designed to be robust with easy and simple maintenance, perfect for koi hobbyists or landscape enthusiasts.

AST filter’s provide both mechanical filtration to remove solids from the water and biological filtration to break down those solids, delivering a seamless filtration process. Engineered for efficiency, AST filters run off of smaller pumps providing measurable energy savings every month.

Pairing an AST filter with a UV sterilizer will achieve optimal filtration and keep your pond clear from free floating algae. Our experts can help you determine the filtration needs for your setup.
