Hi guys . . . My 30 gallon is almost five months old now. Has plenty of live rock with coralline on it in spots. I have a 150 wts metal halide. Had a few spots on the back of the tank but then my bicolor blenny chomped them off ! Will increasing the flow rate and magnesium levels help in more coralline ? I want a nice purple backdrop. Calcium levels and alk is on the normal amount. Pls help !
