Producing Nitrosomonas, Nitrobacter, and Denitrifying bacteria for personal use
I am a koi hobbyist and we use beneficial bacteria in our ponds to make them gin clear. I was curious if I could produce my own bacteria rather than spending $100's on buying them. I assume I need to replicate the same optimal conditions for the bacteria to grow. Ample food, oxygen, temperature, pH, and surface area. And then harvest once the population is large enough. Any assistance would be greatly appreciated.
