This Odyssey Muck Vac water vacuum system is great for maintaining ponds, pools and fountain systems. The Muck-Vac hooks up to your standard hose and removes debris, even pebbles and small leaves. The muck and waste is vacuumed up the telescopic pole and discharged right out the end of the provided discharge hose, into a bucket or into your garden without causing turbidity in the pond water, or displacing fish or plants. It puts no water in the pond. It will remove some of the pond water with the muck and waste. The Muck-Vac is light and easy to use and cuts down on seasonal cleaning time. Easy to use and assemble. No moving parts. Requires minimum 50 PSI garden hose water pressure.
