I started cycling my 29 gallon tank about 3 and a half weeks ago. After establishing a 4" DSB
, I threw in a raw shrimp which stunk up the place after 2 weeks. It was a mushy mess, so I just took it out. At that point, ammonia was up at 3.0 mg
/l and nitrites were off the charts. At the time, my pH was 7.7 and KH
looked good too.
A week later, ammonia has dropped down to almost zero (which is good), but the nitrites still remain at very high levels. How much longer should I expect to wait to see the nitrites fall? I would imagine I should wait until both are at zero before I add cured live rock. Otherwise the organisms on the live rock would be killed?
