What levels (ammonia and nitrate) can the bacteria (aerobic and anaerobic) withstand?
Is there a certain threshold that's known to kill off bacterial colonies, both the aerobic and anaerobic, or is it that new types of bacteria start forming to process higher levels of certain parameters? I suspect that there are different bacteria at different pH levels, but what about ammonia? I've heard that one should be able to process 4ppm within 24 hours, but is there a threshold not to cross? I'm currently at 8ppm wondering if I've killed everything.
I'm also wondering about nitrate, and whether or not that could kill off bacterial colonies, aerobic and anaerobic, or is it that new types form to process the higher levels?
