Hey guys,
I have a 30 gal tank with two cascade 400 internal filters. I have two of them as I cannot afford an external canister filter at the moment and both of these are able to handle up to 40 gal of water. My issue is when I go to clean them, as I'm removing them from their place in the tank, a lot of the gunk and dirt go back into the water, so i'm forced to take out my turtles and put them in a separate tank until i'm finished cleaning. Is there a way to clean the filters without all that gunk going back into the water? Anyone have experience with these sort of filters?
Thanks
