Crystal Clear Biological Clarifier

CrystalClear BioClarifier naturally clears the water, removes odors, and breaks down suspended dead debris and decaying leaves with billions of bacteria colonies and added enzymes. The result is a cleaner pond, happier fish, improved dissolved oxygen levels, and reduced ammonia levels. CrystalClear BioClarifier comes in easy-to-use water-soluble packets and can be used in ponds, fountains, bubblers, and disappearing waterfall features. Use when water temperatures are above 50°F (10C)
