can anyone tell me what this algae type is on my rock? It's hard, like surface of the rock hard. Snails and fish treat it like rock. Tank is 5 months or so old and was started with base rock from reef cleaners. I read someplace that it may be green coralline? I was battling high phosphates for a while at around 1.3. I started dosing 1ml vodka a month ago and now my phosphates read 0. They may be higher as my Hannah tester only reads down to .04. (Bought the wrong Hannah tester) my nitrates are 5 my salt is 1.025 alk is 10 calcium is 405.
