I use the Dennerle Mulmabsauger for my 220L aquarium, which should not be too much confusion gewirbeld because of Aquascaping. I clean so sandy soil, which can be by swirling ideal with this strength of flow without the half sand is drawn from the pool me. Even the remains of plants in the area with Aquasoil can be at a slight distance so just suck without the Aquasoil is tightened.
