Hello iv had a new SW tank running for about 4-5 weeks not with about 37 lb of live rock... two demels and two clows... demels I heard was a great fish to start out with but pretty aggresive. The two clows surprisingly don't seem to mind eachother. But it seems like this is too much for a newly running tank? I just was givin the clows on the spare of the moment and didn't have anywhwere else to put them! Anyways, recently iv upgraded the lighting to a four bulber and put in two power heads which I might think are way too much current so they are both turned to give half the power... they are a 50 and 70 aquaclear heads... iv noticed brownish spots all in substrate as well as the glass near the sand bed. And some shown on the live rock. Its a brownish/yellow dirty tint and I was wondering if this was just a normal process or is something bad happening! I will check water levels with the few test I have when I get home and update the tanks and my progress! Please help me out with what u think it could be!
