Microbe-Lift KH Bio-Active Booster - Maintain Optimal Carbonate Levels for Nitrification in Ponds


Ensure the continuous success of nitrification in your pond with Microbe-Lift KH Bio-Active Booster, an essential solution for maintaining carbonate alkalinity (KH). Ideal for use with tap water, tank water, and during water changes, this booster safeguards the natural biological ammonia removal process known as nitrification.

Key Benefits:

  1. Nitrification Support: The KH Bio-Active Booster is crucial for the nitrification process, ensuring the continuous removal of ammonia in ponds.

  2. pH Stability: By stabilizing pond pH, this booster helps prevent pH fluctuations caused by the depletion of carbonate alkalinity. This is particularly vital when pond carbonate levels fall below the necessary threshold.

  3. Easy Application: Available in various sizes, the booster is conveniently measured with a full flat level scoop (enclosed), making it easy to raise KH levels according to your pond's needs.

  4. Versatile Use: Suitable for tap water, tank water, and water changes, the KH Bio-Active Booster is a versatile solution for maintaining optimal water conditions in various pond setups.

How it Works:

  • Continuous Monitoring: As nitrification depletes KH, it must be monitored regularly. The booster utilizes a proprietary blend of Carbonate Hardness constituents and bacterial cultures to support the natural ammonia removal process.

  • Application Guide: A full flat level scoop raises KH by approximately 80/ppm in 30 gallons, 50/ppm in 50 gallons, and 25/ppm in 100 gallons.

Available Sizes:

  • 2 Lbs. (0.9 kg.) (CABPSM)
  • 8 Lbs. (3.62 kg.) (CABPMD)
  • 20 Lbs. (9.07 kg.) (CABPLG)
