Aqua Ultraviolet Ultima II Filters
With Aqua Ultraviolet’s extensive research and manufacturing capabilities, they have delivered the next generation of the best selling Ultima filters… the Aqua UV Ultima II. Their research has resulted in a patented bio-carrier that provides both high surface area and a non-clumping design. Performing both mechanical and biological filtering, cleaning of accumulated solids is accomplished via “cyclonic” power backwashing of the media. This process both reverses the flow direction and spins the media, resulting in more thorough removal of debris. Designed for high flow rates, heavy fish load with high feed rates, the Ultima II filter is a popular choice for many koi keepers and water gardeners.
Ultima II filters are available in a number of sizes to accommodate various pond sizes and fish loads.
