D-Solv will also keep fountain intakes clean and remove unsightly scum from the perimeter of any size pond. D-Solv is your personal pond cleaner in a bottle, without the time, money, mess, effort to catch the fish, drain the pond, wash and scrub the scum in the pond, refill the pond and put the fish back in hoping you don’t stress them and kill them. This usually 4 – 5 hour process can be eliminated forever by simply treating your pond once weekly with D-Solv.
