ProForm-LA is the safest and most effective treatment for the control of diseases of pond fish caused by Lice and Anchor Worms.
It is just as safe to use on pond fish as Dimilin, yet it is much safer for human contact. It will not harm reptiles (turtles), amphibians (frogs) and mollusks (snails). When used as directed, it will not harm biological filtration and may be used with "scaleless" fishes such as doitsu koi.
After the water temperature in your pond drops to 60 degrees or below, you should decrease the amount of food given to your fish and feed them no more than once a day using a food designed for cool weather feeding.
