Hello Everyone, about 6 weeks ago I decided to put Sponges in my filters just as extra along with the regular filter media. They're the kind you buy @ the store for household cleaning but without the scrub side, now whenever I open my tank lids it smells like an old dirty dish rag!!!! Should I remove them? My fish seem to be doing ok and all my params are good, I just don't think I can take the smell! :-( I also swish them around in tank water @ least once a week when I do PWC
's anyone else had this problem?
