Ultima II systems are packed with ultra-high filtration bio-media that provides both mechanical and biological filtration, ideal for aquariums and fish ponds. The advantage of the Ultima II filter is it´s non-organic filter media with properties that encourage bacteria growth. The disadvantage of conventional bead filters is they have only a single-surface area which encourages a second layer of bacteria to grow over the initial layer. The enclapsulated bacteria underneath can become anaerobic. This continuous cycle can pose problems. Research led to three different types of media designed to grow and hold amonia-oxidizing bacteria and heterothropic bacteria. Just one cubic foot of these three media has over two million tiny shapes. One cubic foot of Ultima II Media is equal to 750 square feet of surface area. The Ultima II system is designed to offer you exceptionally clear water, great for ponds and aquariums. Cleaning is done by internal jet back-washing.
