UltraClear Barley Pellets offer a safe, effective, natural way to treat ponds for clarity and can be safely used with all other UltraClear products. The pellets are cleaner and easier to use than the bales (and requires a lot less space than the unsightly bales). UltraClear Barley Pellets are 100% safe for fish, birds and plants. UltraClear Barley Pellets are fortified with humic acid prior to the pelletizing process. Humic acid enhances water quality, water softening and balances out the effects of phosphate in the pond water. The slow decay of the barley pellets produce essential, beneficial bacteria that helps maintain clarity in the pond. The optimized pellet size offers maximum surface area for controlled decay. It is not a chemical. UltraClear Barley Pellets can be used during spring, summer and fall. Apply 8 to 16 ounces per 100 gallons every 4-6 weeks or as needed. UltraClear Barley Pellets can be applied directly in the pond or in the skimmer or filter utilizing a media bag.
