I have a 130G fairly new tank that I did a fishless cycle on. Went fairly quickly and was able to watch Ammonia, Nitrites, and Nitrates spike as I should. Used Eco Complete, some substrate from an old tank, and Microbacter, (and did it fishless). Now however a couple weeks later I am seeing this...
Nitrite .25 - .50
Nitrate 10 ppm
So my question is whats up? I have heard of spikes that happen post cycle and maybe this is it. But if it IS, then why am I having high(ish) ammonia readings? Should I just let the bacteria do its thing? Should I Prime the whole tank to neutralize the ammonia for the fish or should I let the process work? Its a moderately planted tank. Thanks!
