[dewboy1127]

So from beginning set up of my tank i started to grow coralline everywhere my back glass at one point was covered. ...now i hardly have any on glass or overflow or anything for that matter. ..what couldve happened? ?..i dont have anything that eats it that i know of

Asternia starfish will eat it as well as some urchins.

High po4 prevents its growth. As little as .03ppm is enough to slow it or stop it in an article i read.

Well i guess those could be my culprits ...i do have some them pain in butt starfish wish could get rid of them without manually picking them out...i do keep a lil phos level in my tank as well
