ESSENTIAL TECHNICAL INFO
The true nitrifying bacteria in Colony can resist up to .20 mg/l. A drop off in nitrification will occur after introducing copper, but will return to normal soon.
Items Not Safe With Colony
Antibiotics, chlorine, chloramine, benzalkonium chloride, potassium permanganate, formalin, copper, malachite green, methylene blue and acriflavine. It is always best to inquire with Blue Shark’s biological specialists about any new products on the market not listed and that you are unsure about.
Colony is compatible with all Blue Shark formulas. It is recommended that Colony is not used in conjunction with SFS based water conditioners that destroy ammonia and nitrite. These conditioners utilize reducing agents that result in unstable food source for the bacteria and deplete oxygen in higher doses which inhibits the aerobic true nitrifying bacteria in Colony.
