Here’s and an easy trick to remove string algae from your waterfall in your pond.
Turn off your pond pump that powers your waterfall. Sprinkle CrystalClear AlgaeOff on the algae and let it sit for 20-30 minutes. Turn the pond pump on and the string algae should wash off the waterfall into the pond.
You may want to physically remove the algae from the water garden and use a clean-up bacteria such as CrystalClear Biological Clarifier to eat up any algae that you missed.
Both AlgaeOff and Biological Clarifer are safe for fish and plants and can be used at the same time with great results. Every water garden or pond owner should have both products.
