Hozelock Bioforce Revolution Pond Filter 6000

The Hozelock Bioforce Revolution was brand new to the market in Spring 2013 and it proved remarkably successful.Quote REV in shopping basket for free delivery.It introduces a clever new concept the filter sponges are tiny cubes rather than solid rings. When the pump is flowing through the pond filter the sponges work as effective debris collectors just as traditional solid block sponges. BUT switch the pump off and turn the cleaning handle and the sponges break up and collide together dislodging debris. Simply switch to 'waste' and switch your pump back on and watch the dirty water leave your system.Because of this effect cleaning mechanism this pressure filter can be used in koi ponds or ornamentalgoldfish ponds.
