in my tank the rocks, glass and sand started to turn red. i cleaned it up and the next morning it was just as bad as it was before i cleaned it. and its been this way for about a week. what is it and why is it there? anything i can to get rid of it? the tank is almost 9 weeks old. i was putting iodine in the water for my coral like the lfs said to. then a couple days later the red stuff came.
Another thing is my fine bubble corals bubbles bust in the afternoon and then the next morning they come back out. is that normal or am i doing something wrong for it to do it. its up on a rock and has good lighting all the time.
