I specifically use propeller aquatic herbicide for water meal and other unwanted plants in and around my pond. i use copper sulfate to treat the algae. a g. Use barley straw. barley straw is becoming an increasingly popular method for naturally inhibiting algae growth. while it can’t kill existing algae, it can prevent new growth. when exposed to sunlight and oxygen, barley straw produces a chemical that limits algae growth, but not the growth of aquatic plants.
Rake out the algae. this is the simplest solution to safely remove algae. just grab a rake or skimming tool and manually remove as much algae as you can from the surface of the water. if your pond has a rubber pond liner, use a plastic rake to avoid accidental tears (a metal rake can be used with a concrete liner). Rinsing my pond filter with the hose. step 5: use hydrogen peroxide (h2o2): it takes a few weeks for the barley straw to work. so, to clear your pond water faster, use hydrogen peroxide (and no, it won’t kill your fish). pour it right next to the fountain or waterfall to disperse it. All work to remove algae from your pond and keep it clean and clear for up to six months, so the one you choose is largely up to personal preference. barley straw for ponds; barley straw extract; barley straw pellets; add beneficial bacteria: excess nutrients mixed with sunlight are usually the cause of algae blooms in ponds. Methods for controlling sunlight exposure: floating plants: adding floating plants like water lilies or duckweed can provide natural shade, reducing the amount of sunlight that penetrates the water. pond dye: pond dye can be used to color the water, reducing sunlight penetration and inhibiting algae growth.
