I've got a growth of some sort thats been growing for about 2 weeks now, its a deep maroon color and is on my rock and is now about the size of a quarter. I've read that cyano should blow away if you point a powerhead at it, this dosent. Should it blow away like a dust if it is cyano? Or blow off the rock in chunks? I've heard of red coraline but I dont know. I doubt if i'm that lucky. Heres a bad pic of it thats probably no help at all. Any input is appreciated, Thanks,
Tim

if its hard and not easy to scratch off, its coraline, it its not, then its probably cyano

cyano is slimey --coralline is not. Cyano comes form light and 'trates. How to reduce 'trates is a very long discussion but the easiest way is not to under-stock your tank with fish.

Not to understock? I've got a 55 gal. tank with a 20 gal sump with a pair of clowns, a damsel, 1 pep shrimp, a serpent star, 2 snails and 3 small hermits, do you think that would be understocked or about right?

Not to OVERSTOCK your tank is what Sen meant. You are understocked.

You can also use chaeto in your fuge or sump to reduce nitrates.

Yep, I've got a boatload of cheato in the sump, my trates are always reading right around 0.
