How do i clean my 5 gallon fish tank?
well for one thing you didn’t say what kind of fish were in it and you should get another tank (and pump if needed) and put the fish in that then dump out all the h2o in the dirty tank and put fresh water in it and a little vinegar too dump that out rise it well and fill it up w/ exceptable water and there you go dont forget to put your fish back in lol
