As a backpack filter highly recommended. I run the filter to a 100L tank. Superlight and clean it. No space claim in the basin, silent and moved the water neatly. The 3 filter media concern for a perfectly clear water. Once a month, rinse the filter, clean the sponge, change once a year, the coal and the biofilter, which is enough perfectly. The operation is very quiet (bedroom suitable). I kannn recommend this filter.
