This pond filter threatens to \'stir up\' the pondkeeping world! Based on the bestselling PondXpert SpinClean filter this \'PLUS\' model includes an in-built motor which cleans the foam filters for you. Once the filter foams are full of dirt and need cleaning a red indicator button will display. Simply switch off the pump and turn outlet to \'waste\'. The cleaning paddle then activates for 3 minutes cleaning dirt out of the foam filters. Listen for the \'beep\' to indicate cleaning has finished. Then switch on your pump to push the dirty water to waste. Once the water runs clear you can switch pump off - turn outlet back to pond and switch the pump back on again. So easy - reduces all physical effort! We love this filter and hope you will too. NOTE: UVC bulb included.
