Biological filters: Replace the carbon when the aquarium water turns cloudy, or at least once every two months. Chemical filters: Give the chemical filter a good cleaning out when it appears to be clogged, malfunctioning or working very slowly. More frequent cleanings may be needed if your fish is sick.
You treat for a week, then do a 25 percent water change. If the fish are not well, treat for another week. In about an hour or so, your tank will look clear again.Please do not do any water changes at this stage.he water will not even be blue at all. Do another 25 percent change, but this time put back the carbon filter. The carbon filter removes any left over medication. If you leave the carbon filter (black filter) in the tank, the carbon simply sucks up the medicine and your fish will not be treated.
