8 lb Block

THE SOLUTION TO YOUR WATER QUALITY ISSUES. Our 8lb Block offers ongoing bacterial maintenance and is designed to provide time-released addition of beneficial bacteria to your body of water. The bacteria will help maintain a proper biological balance in the water by improving dissolved oxygen (DO) levels and helping to reduce ammonia and nitrite levels, as well as noxious odors caused by hydrogen sulfide, dead plant material, and fish waste. Additionally, these bacteria will help with the continued digestion of organic matter in the sediment.
