This filter unit from Aquacomputer has a great advantage in practicality compared to standard, more simple, filters: Two integrated valves allows easy cleaning of the filter without draining of the whole system. The stainless steel filter mesh with an exceptionally large surface area is extremely durable and can easily be removed for cleaning. The Plexi cover allows visual control of the state of the filter. The large filter surface also results in a very low flow resistance. A mounting plate for installation in the case is included. Lighting possibilities are given by the G1/8" thread at the bottom of the filter unit.
