I just had a look at one of my corals today, and there is a nice big green patch and IMO does not look quite healthy. \n\n[IMG]http://img402.imageshack.us/img402/4912/010dg.jpg[/IMG]\n\nI get a feeling this is because the guy who sold me the tank said it would be completely setup for corals, but on my own inspection after reading the forums, I think I have nowhere near enough light. \n\nIve got a T5 light, but he only gave me 2x 24W globes and my tank is 60g\n\nill be going to upgrade this very soon because it sounds stupid having under a W per gallon \n\nWhat do you guys think? is this t he cause? or could it be something else? \n\nMy testing kit for everything is still coming in the mail and should be here early in the week, so i havent tested my water recently, but everything else seems to be doing quite well except this one.
