CrystalClear Nature's Choice Barley Straw Pellets utilize barley degradation technology to help manage ponds all year long. When placed in an area of steady water flow CrystalClear Nature's Choice will slowly degrade and emit a natural chemical that cleans and polishes pond water naturally.
Add 1/2 lb of pellets per 500 gallons every 3 months to the media bag, included. Place near waterfall or where water returns into the pond.
