media baskets?

Floss and Carbon though carbon is completely your choice, some put Zeolite in there but I dont know what it does :joe:

Mainly, put floss in the first chamber to act as a mechanical filter. In the second, you can put a sponge to work as a bacterial substrate as a biological filter.

You can add more things after the sponge. for example:

- Activated carbon/charcoal is a chemichal cleaner. Useful to remove medications from the tank. Its use is a good debate among fish keepers.

- Zeolite: it absobrs ammonia. useful to control ammonia spikes.

A canister filter should work perfectly only with the floss and sponge, as long as you don't overfeed or overcrowd the tank, and you do your routine water changes,

I just put some purigen in one of my media baskets and the other basket has a sponge to grow nitrifying bacteria in case I want to use my hospital/qt tank. Prevents me from having to cycle the tank.
