This set contains two superb Laguna products. The pressure filter provided uses a high-powered 11w UVC bulb. and can be cleaned without opening the lid. This is achieved by simply switching to \'waste\' mode and then scrubbing the dirty filter sponges via the external handles. The dirty water then exits via the special waste outlet (see attached pictures). The pump can handle 6mm solids and boasts low running costs. This set contains the following components (please click links below for more information): • Laguna Max-Flo 2200 pond pump • Laguna Pressure-Flo 3000 pressure filter * Saving made when compared to buying items separately.
