Oase Biosmart filters include Oase distinctive filter foams, with maximum surface area for beneficial bacteria which transform toxic ammonia and nitrate into harmless nitrogen.
The filter media is available in two formats, a red fine foam which is perfect for catching the smaller pieces of dirt and grime, and the blue foam which is coarser and will catch large pieces of waste. The foams are ordered singly to make up the desired filtration scheme in your filter and to make sure that your pond is beautifully clean and clear.
The foams sit easily together inside the filter unit, and slot easily into place thanks to the corrugated edges. This forms a tight structure that ensures the water is fully cleaned. Foams are easily squeezed clean by the innovative compression system built into the filter. Simply turn the handle and the dirty water is squeezed out.
