The exposed sponge is much easier to clean than the full mattenfilter but it is still visible equipment and does not hide the heater (which the angels lay on) so it is not the ideal solution but it works. I also have a powerhead mounted normal with a sponge in my 20 long. I guess I will have to call it the reverse-Wasserfilter
Anyways, the documentation on Wasser-wear is always first rate.

Of course, an internal filter with a sponge is nothing really new... it's just that sometimes we forget that "simple is beautiful".
