Biological Clarifier (Crystal Clear)

Crystal Clear Biological Clarifier 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, healthier fish, improved dissolved oxygen levels and reduced ammonia levels. This product 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. Apply product once every 1-2 weeks. For ponds with more persistent problems apply once every 3 days.
