AbelR1975 Posted August 5, 2014 Share Posted August 5, 2014 I'm not sure what these things are on my rocks. They have just started appearing. They are kind of yellowish/green...leaning more towards the yellow. Any ideas? Quote Link to comment Share on other sites More sharing options...

AbelR1975 Posted August 5, 2014 Author Share Posted August 5, 2014 Ok. Thanks! I'm very new to saltwater (just a little over a month). I got my setup from a friend who didn't have the time to maintain the tank. The tank and all the rocks were COVERED with Majano. I nuked most of the rocks, but left a few that I had managed to clean in the tank and the sump. After all that, I get VERY nervous whenever something new pops up. lol Quote Link to comment Share on other sites More sharing options...
