For years I had large aquariums (several hundred liters), and had reasons of space recently to 60 liters "downgrade", connected to a Aquascaping-switch. A small pool is maintenance intensive than a large, but knowing the aquarium among readers already. Anyway, the Mulmabsaugen was quite cumbersome with my old sediment bell, also uprooted the strong suction force almost ground cover! The Dennerle gravel cleaner is awesome, well thought out everything to squeeze suction easily by a few pumpings, the bucket clamp prevents floods, the hose clamp regulates the flow a little rough, but still easier than a thick plastic tube awkward with the (third?) Free hand together , Thanks to the flow control I could my pool of sludge free without for a few minutes before a waterless aquarium to have. With the lean intake I'm going come in every corner and there it is transparent I see exactly what is aspirated. My bowl is 40 cm high and the hands remained dry at work. For higher basin probably less suitable. From me anyway uneingschränkte a buy recommendation!
