3-room apartment

Comfortable, modern and profitable! Assembling a filter for any aquarium. 3-8 degrees of purification, high efficiency, water quality is higher than that of simple filters, wash 1 time in 3-4 months, change filter materials 1 time in 5-6 months. The size of the filter and the price is calculated according to the volume of the aquarium. It is cheaper than buying a biofilter in a store. My photos.
