Natru-Sal is a natural salt that activates and supports a number of important processes in the pond environment. It prevents extreme pH fluctuations, allowing microorganisms to develop better and the nitrification process to continue. High ammonium (NH4) concentrations and nitrite (NO2) poisoning are thus avoided.Natru-Sal is also ideal for fish stock as it activates the mucous membrane of the fish and prevents the penetration of mold and parasites. It reduces stress levels during overpopulation and when transferring new fish into the pond. In addition, Natru-Sal supports and intensifies the effect of medication in the pond. With Natru-Sal you can be sure that your pond environment remains healthy and balanced. Use Natru-Sal to optimally care for your pond and give your fish a healthy and stress-free life.
