Probiotic and nitrifying bacteria Tropic Marin ® NITRIBIOTIC is a combination of probiotic and nitrifying bacteria in one preparation which strengthens the defences of the immune system of fish and shrimps and improves the water quality. The nitrifying bacteria efficiently start the nitrification process, i.e. the process of breaking toxic ammonia down into non-toxic nitrate. The purple bacteria contained in NITRIBIOTIC oxidises toxic hydrogen sulphide to non-toxic sulphur and sulphate. Probiotic bacteria and yeasts have a proven positive effect on the health and well-being of fish and shrimps, especially when breeding.
