A full de-sludge is also available by simple hose attachment (all filter media is held above the filter floor so valuable friendly bacteria will not be harmed by this process). The new Hozelock Aquaforce can handle solids up to 6mm and has very low running costs - just 50w.Save £34.99 compared to buying items separately
