I put in 50 LBS of live sand over 48 hrs ago and i still can't see the rocks inside because of how cloudy it is. I turned my power heads off for a day and it improved a bit but nothing like it should. My question is, should i keep running my power heads or leave them off? Also, I am using dry rock, what is the best chemical i can use to get good bacteria to start to grow on them? I don't think the live sand will be enough but I could be wrong. Thanks in advanced for any help!
