Hey everyone. Quick question.
I recently bought a couple of tanks and a box of supplies at a yard sale.
There were a couple of filters in there.
I set one uo on a 20g. The lid says Secondnature Whisper Power Filter.
On the part that covers the intake is the number 2.
It came with a bunch of filter pouches.
I know they hold carbon or I can use floss or whatever in there.
I thought the sponges were missing.
I googled the heck out of this filter and couldn't find anything about a bio-sponge. Went shopping today and couldn't find any made for this filter so I bought some I'll cut to fit.
While at at the store the girl said some of the filters only take the pouch not both.

I know their smaller filters are like that.
So I get home, look in the filter and sure enough, there's no place for the sponge.
Am I missing something or were they really made just to have the pouch?
I plan on sticking a seeded sponge in the pouch. How's that sound?
Thanks!
