Well I have a Fluval 405 as one of my filter on my 120 gallon tank. I have this problem when I change my filter media and clean my filter after I clean and everything....when the water starts flowing all this crap comes out from the output hose. The stuff must be from the filter or from the hoses. It gets all over the water and flats arounds for days.
How can I avoid this ?
Does this happen to anyone else?
