Aqua UV Ultima II Filters
Bio-Mechanical Pond Filters
The Aqua UV Ultima II Pond Filter is the next generation of bio-mechanical pond filters, made to handle extreme loads and high flow rates with ease. Designed for koi ponds, aquaculture facilities, large aquariums, and residential or commercial water features, the Ultima II keeps water crystal clear and safe for aquatic life. With its patented cyclonic backwash system, simply set the valve to backwash and rinse, the internal jets clean the media automatically. With no dismantling or scrubbing, these pond biofiltration systems keep your water clean and healthy.
Balanced Aquatic Ecosystem
The Ultima II doesn’t just trap debris, it’s seeded with beneficial bacteria that transform harmful ammonia into harmless nitrates, creating a balanced ecosystem where fish thrive. The unique tubular filter media, designed with a patented “Y” shape and protective wings, offers maximum surface area while resisting clogging, even under backwash. With one cubic foot of media providing 750 sq ft of biofilm surface, these easy-clean pond filters deliver unmatched efficiency and long-lasting performance. For a clean installation, the filter can be discreetly buried up to the valve assembly.
