Is this good algae? ID PLEASE

[-=James=-]

Thanks Myka. I have looked at your links a few times.

When you say lower nutrients, do you mean less feeding? I have no fish or anything and wont have any for another couple months. I have a few crabs, large turbo snail, brittle stars/worms. Could I buy some more inverts to help?

Also, what do you think about putting rocks with hair algae (not pictured) in a tub and letting it sit in the dark for a week or so? I am in the process of doing that but not really seeing any results. I do see some little worms and polyps at night too.
