Looks like your tank is fairly new. I can't make it out in the pics too well. Is it hard or soft and easily removed?

I tank brush easly removes it off the glass and looks soft. only time my hand goes in is when I add rock or feed my nem

If it brushes off easily then it's not coraline unfortunately. What do you mean when you add rock? Are you adding rock without curing it? How old is your tank? Need a much better pic to help identify. Google cyanobacteria and see if it matches that.

There is a couple of products you can use but you may want to consider adding more flow and watch how much you are feeding.

Tank is olmost 2 months old. 1 cube of frozen food and a small pice of frozen krill for the nem. Don't have the reef masters kit yet but ammonia is barly showing up along with the rest PH is 8.2/8.4. Only have maby 20 lb of rock in my 50g. 3 fish 2 Clark clowns and a dragon goby a small clean up crew as i plan on getting a puffer so he will eat them any ways. Have my return hitting the top at about 300gph and a 450 gph prop on the other side pushing waist up to the drain. Also have a 50g sump with a 5 in deep cc and a skimmer tho the sump has many 30g in it so about 80 g total volume. I get cured rock from my LFS. At little over $6 a pound or I get the life rock at about $5 a pound tho I don't cure the life rock. Yes I am adding rock as I go I know I can see my phosphates jump which can lead to more algie but that's ok I can work with it
