WipeOut™ is excellent for controlling gill diseases in pond and aquarium

water quality conditions (pH, oxygen or temperature problems), habitat
clean-outs, untreated abrasions or predators. WipeOut™ works extremely
well on pond fish species such as koi and goldfish as well as on commonly
found aquarium fish species.
