PondMagic Oxy Pond Cleaner - Cleans Rocks, Pots & Liner On Contact

Works So Fast You'll Swear it's Magic!

Don’t you wish you could snap your fingers and magically every surface of your pond was like new? Well you are in luck. SuperNatural’s PondMagic will do just that by utilizing ONLY OXYGEN! PondMagic is a white powder that oxidizes and removes algae and organic debris on contact. Just apply it on any surface, rocks, liner, waterfalls, streams, fountains or bubblers and watch unsightly debris vanish. Simply turn off your pump and sprinkle PondMagic wherever it's needed. After a few seconds, it starts to bubble and “Poof!” that's when the magic begins. After 10-15 minutes you'll have clean surfaces. 1/4 of a cup treats 100 square feet. Use as needed as problems arise or to fight on-going issues within the pond.

Pond Magic - rock cleaner

You can also use a weekly maintenance dose of PondMagic to eliminate the need for complete pond clean-outs forever. PondMagic saves you 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 lengthy process can be eliminated forever by simply treating your pond once weekly with PondMagic. PondMagic will also keep fountain intakes clean and remove unsightly scum from the perimeter of any size pond.

PondMagic is manufactured following Good Manufacturing Processes for “General Principles of Food Hygiene”. Failure to use as directed on label or changes in water conditions not consistent with label may result in loss or injury to aquatic life. SuperNatural is not responsible for any loss or injury to aquatic life. Keep out of reach of children.
