Aqua One ‘wool’ filter are actually composed of fine polymer fibres that will not rot in water and have a long, effective operating life. The pads are designed to trap solids and should be discarded when filled with waste and debris. Rinsing this fine polymer works well and refitting an old, flat polymer wool filter will decrease the filter flow rate and re-introduce old waste matter and reduce the operating life of the filter.
A fresh polymer wool filter each month will improve water quality and clarity, maximise filter flow and prevent blockages and over flows. This will reduce your work load and keep your set up looking its very best.
