The HMF – What's That? — Seriously Fish

Hamburg Mattenfilter for quarantine?

The sponge filter is a mechanical filter and the surface of all the bubbles or pockets in the sponge provide biological filtration. Sponge filter produces minimal current and has almost no way to suck the fish through the filter which is excellent for small size fish. And it is very easy to use, just connect the unit with an air pump thru airline tubing and turn on the pump. Note: You need to squeeze the sponge several times in tank water for easy sinking.
