Hi everyone. I have some very 'noobie' questions. We are using a Secondnature Whisper Power Filter. We buy the bags that go over the frame and then pour the charcoal in. We also have a undergravel power head thing. Now I know this will sound stupid, but shouldn't there be some kind of filter between the stuff the power head sucks down and then what it blows back out? We bought it at our local pet store (not chain) and they didn't ask or mention anything else to get.

It just seems weird. Plus, curiosity got the best of me and I looked at the under side of the tank. Ugh!!!!!

So, if I missed the part of using a filter with and undergravel powerhead, please let me know.

. Thanks
Debbie
