Hey, I know I've got an aqua clear filter already but I hear some people say that the penguin filters are a lot better and others say they aren't the best.... my pet store uses them and they seem to be really good although the other pet store uses the aqua clear filters and they seem to be keeping the water clear. it keeps my water pretty clear too unless there is a bacterial bloom So, do you think the penguin filters with the bio wheel are better? since there is a bio wheel that does something to the water I suppose.... I don't know what it does exactly. If the penguin filters are better, than I will switch to those filters and probably give my filters away So, tell me what you all think penguin or aqua clear?
