I have been using this filter for 12 months now and it is quite big enough for my small pond. However the water quality has gradually worsened despite pumping it every week. I recently noticed that after the pumping cycle and the water was turned back on that for the first 30 seconds the water going back into the pond was dirty! My neighbour suggested that I should run the first few gallons of water to waste which I have done and it seems to have worked. Why should this happen and has anybody else had problems with this pump? Thanks, Rob.
