Okay, here is the situation. I put together my tank a week ago. I used some partially cured tonga and some well cured/aged marshall live rock. I only saw a little ammonia spike and now my ammonia and nitrite are 0 and my nitrate is at around 10 ppm. I have hair algae growing on some of the rock and brown algae(?) on the top of the sand bed. Could the tank really be cycled already? Also, I am planning on adding the CUC in about another week. How long should I wait to add corals and fish? There is definitely some die off still occuring on the tonga rock. I am using a skimmer and I have a refuge but have not added any cheato to it. Anybody got some cheato they could part with?
