Did this type of filter is now in all dwarf shrimp pools and do not want to miss it. In contrast to the state of versions of other manufacturers, we feel it as save space. The height of the "outflow" is variable, so that as required the Schaumstoffilterung can attach higher or close to the ground. You can tell the filter to when the cartridge is easily soaked, then, the number of air bubbles in the tube significantly. Cleaning is also fast. Just off the pool cartridge and raise again. Then bring the suction cups back into position and the filter sucks like at the beginning of the water well. We use the filter usually in 30 liter tank. For a 60 gallon tank, it is advisable to run it after our experience 2.
