The maxspect sk200 skimmer is installed to a depth of 16-17 cm, the pump capacity is 80%, the drain is fully open. the water/foam level is set at the bottom of the bowl. after a few days, the water level rises to the middle of the bowl. if you disassemble and flush the channels for draining the water, the level is normal again. but after a few days it rises again. As a result, the foam becomes more "wet"
