Algea identification coralline or??

[Andrew Sizemore]

ByI have some of what looks like purple coralline growth but I'm now getting a ton of green algea that makes me a little worried its lime green no bubbles no hair, just looks like someone painted my rocks green. Its a 75 gallon used dry rock not live rock, no sump only hang on back filter and protein skimmer. Its been running with no ammonia no nitrates or nitrates for about 2 months I have corals and fish already. I will add close up pics later today.

It sounds like green coralline. My tanks developed the green stuff before switching over to the reds. Seems to be common.
