I'm a newbie with my first question. In both of my tanks(29g and a 10g) there seems to be excess algae growth on the live rock (brown & green, & some bubble caulerpa). Livestock includes hermit crabs in both tanks, 2 chromis fish in each tanks. Are the fish causing the algae bloom (nitrite, nitrate)? The tanks are both about 2.5 months old, and I've read that this is normal for new tanks, however, when does it subside? I would rather not use a chemical to kill the algae, so shold I just ride it out? In the 29g there is ~45lbs live rock, ~40lbs live sand, 3 power heads, Remora hang on skimmer, 150w heater, Coralife c.f. w/ 65w 10,000k, 65w actinic. I have to figure out how to post my tank info w/ my user name? Well, I'm glad that I found out about this website, it rocks. Hope to hear from some pro's!
