I have an AquaClear 70 HOB attached to my 55 gallon corner tank. I have the coarse sponge, charcoal, and biomax media installed in the filter. Is there any one of those that shouldn't be in there? Is there anything that is missing? And I heard that I am supposed to do maintenance on the filter only once a month to swish the media out in old fish tank water?
