The Aqua Ultraviolet Ultima II Filter is specifically engineered to meet the environmental demands of aquatic life. The patented Aqua Ultraviolet Ultima II Filter does the work of two, combining biological and mechanical filtration into one compact package.
The internal components are designed to accommodate high flow and heavy solids that occur naturally when aquatic life is present. The patented cyclonic action is generated by jets activated during the backwash cycle. This action blasts the media apart, then lifts and spins it, separating the waste and flushing it away.
The Aqua Ultraviolet Ultima II patented tubular media design has the highest surface area on the market to grow beneficial bacteria. These bacteria break down fish waste, creating a safe healthy environment. During the backwash cycle, the media's design prevents clumping and protects beneficial bacteria. Independent laboratory and Field testing has shown the Aqua Ultraviolet Ultima II out performs all other filters on the market.
You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
