how to kill ich in your aquarium for good.
ich is a parasite that lives in your aquarium.
ich will kill your fish in a matter of a few days.
water parameters could be great and you water can look great but the parasite is there.
removing all the fish from your main tank removes the food source for the ich parasite....and the parasite will die.
your fish will swim in a copper solution by seachem, in a separate tank, to cure them.
there is confusion on how to dose seachem cupramine.
i do not recommend fresh water dips for your saltwater fish. it stresses them out and doesn't do much.
copper solution cupramine by seachem to kill ich.
I mean to type "Quarantine / Hospital tank" in that last line!
