Tropic MarinĀ® 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.
Tropic MarinĀ® NITRIBIOTIC contains Bacillus subtilis, Nitrobacteria, Saccharomyces, Lactobacillus and Purple bacteria.
Application and dosage
Shake the bottle well before each use! To enable the bacteria to develop unimpeded in the aquarium, turn off UV systems, ozonisers and skimmers before dosing and only turn on again 3-4 hours after dosing. NITRIBIOTIC can be dosed into the inlet of a biological filter or directly into the aquarium water. Attach the enclosed hose to the syringe and measure the desired amount of NITRIBIOTIC with the syringe. The air that gets into the hose and syringe while pulling the syringe, does not affect the dosage. The bottom edge of the plunger always displays the correct dosing amount even if the desired quantity of NITRIBIOTIC, due to the air drawn in, is only in the hose and not in the syringe chamber. The air drawn in serves to empty the hose during dosing.
