Revive is a low-cost, highly effective biological water treatment product developed specifically to enhance water quality. The balanced blend of bacteria, bacterial enzymes and nutrients utilizes the available nitrogen and phosphorous in a water body, improving water clarity and reducing organic sediment build up and odors in ponds. Revive is also an excellent product where a biological amendment is needed to extend the use of copper and dye applications. Revive helps re-establish a healthy balanced aquatic ecosystem. It's all-natural and will not harm fish, animals, birds, plants or humans.
