First sponge filter

[johnj55]

I just placed a sponge filter in a new tank. No fish or plants yet. Should I have a overflow filter along with the sponge.

Many breeders only run sponge filters, but a small Aquaclear filter would give you more room for biological bacteria. More filtration is a good thing.

Just set it up today sponge and sand. It's still a little cloudy

Haven't used sponge filters myself, but I have one thinking of using it on a 20 Long for mystery snail breeding/grow tank?
