this tank has been setup for about a month and a half. salt has been in and stable for a month. I have about 35-40 pounds of live rock in there with no fish yet. my question is...why is my sand starting to get patches of brown? I swear it was fine yesterday. My pH is low.....7.8 or so. As for the other water parameters....i haven't checked yet. I just got a full kit today and wont be home again til tomorrow. The lights are on 5 hours a day for now, but they are just standard flourescent bulbs I've also done a water change of 5 gallons for the last 3 weeks. Do these brown spots mean my tank is cycling, and will they clear up?
