I don't know if you'd be interested in doing this or not, or even if it is possible with the type of hang-on filter that you are using, but after I lost a number of impellers due to sand getting lodged in the impeller housing, and stripping the plastic from the impeller, I got smart and totally removed the impeller, and unplugged the unit. Instead of using an impeller to suck up water through the lift tube part of the filter, I have attached a Penguin 1140 powerhead to each of my Penguin 330 Bio-Wheel filters, so that instead of water being sucked up by the impeller, it is in fact pushed up from the strainer end of the filter. In other words, the outflow part of the powerhead is connected directly to the intake of the filter's lift tube with a short rubber hose -- which is totally invisible -- while the strainer piece which normally connects to the end of the filter's lift tube, is connected to the intake of the powerhead. This prevents sand from clogging the impeller in the filter, being as there is no impeller there to begin with. If you are familiar with Penguin filters, then you'll know what I am talking about. MG> Cichlids also do well here in Alberta because our water is hard, which is MG> what they prefer. I wasn't aware of the fact that water is hard in your part of the world. Where I lived as a kid in the Eastern USA, it was relatively soft and acidic, as I recall. But that was many years ago, so I could be wrong.
