Is this green hair algae?
I'd like to nip the problem in the bud, if I can.
Doing some reading, looks like these are my options: - reduce the photo period - add a CUC or tang - increase water changes (I did about 20% last week, planning same this week) - manually vacuum it off I think in most cases these are only ways to reduce the symptoms rather than fix the overall problem. I don't have a phosphate test kit yet, but I will be picking one up tomorrow (ammonia, nitrites, and nitrites all read 0). At any rate, I am using RO/DI water so I am confused with the source of the phosphate would be. I did start with mostly Marco rock, which I did not cook as I was under the assumption I did not have to. Would appreciate your feedback, thanks in advance!

Thats definitely some interesting growth patterns for an algae. It looks green, but it could be macro instead of hair. Have you tried touching it? I find that hair algae tends to be more slimy, as opposed to macro which doesnt really feel that way.
I would siphon it off, or brush it off with a tooth brush (last resort, provided you have good flow and strong skimming). Perhaps you could post a picture that isnt so blue, if possible? Kinda makes it hard to see the green

did you use Dry rock? What are your phosphates at? Might me time to start using a phosphate remover if you aren't already. If your cycling a tank you could always leave the lights off to keep it at bay while you figure out if your rocks are leaching nutrients

Looks like your rock is still dead, so no problem to remove the rock for a minute and blast that spot of algae with a blowtorch. Do it now as its easier to remove that piece of rock now rather than later.

I would just use my clippers and cut that little piece of the rock out.

Good to know. I'll start removing tomorrow during my water change. So far I only see one clump, but I imagine more are to come.
I think I will try a mesh bag filled with GFO. Obviously it won't be as effective as a reactor, however I'm guessing it's better than nothing. I don't have the heart to plumb in reactors, nor do I have the room.
