Microbe-Lift Maximum Clarity is a 100% natural blend of bacteria, enzymes and buffering agents. Microbe-Lift MC should be applied directly over the surface area of the pond. It can also be spread around the pond's perimeter. The bacteria in Microbe-Lift MC are grown on a bran base. This will cause cloudiness in the pond after each application. The pond will clear up within 24-48 hours.
