Hello all, I am curious about supplements....Calcium, Magnesium, Strontium and other Trace Elements. I am new to the Reefing/Salt tanks. Ours is 11 month old now and seems to be finally stabilizing. However, still feels like I dont know enough.....We have a toadstool, galaxia, torch, hammer...

HI, are there any good supplements out there that will help my liverock spread more Coraline algae faster? i only have a few purple spots on my live rock.
