O.K heres my question, I have been running my tank now for 2 weeks and been testing everyday. My PH is 8.3, ammonia 0, nitrate,nitrites both 0. Theres hasn't been any spikes the only thing I'm getting is green algea and I think that is from running the light for 12 hours a day, I'm running them 8 now. So should I go get my clean up crew or just wait. I started with 20# live sand and about 25# of live rock, I have a jbj 28. The only thing I can think of is my live rock came straight from a established tank. Oh one other question what would be a good clean up crew for a tank this size. This is my first tank ever.
