Some sort of green algae

[jferr020]

I have a 14 gallon nano tank that has been running for 5 months. I have 2 clowns, a YMG and a peppermint shrimp. Two zoas and a clove polyp. My CUC is copepods, conch and 3 snail, one is a nassarius (not sure what the other two are).
I have been battling this algae for a month ( images below) The algae is mostly on my rocks and glass. The conch and snails are getting 75% of it by night and it comes back.
If this is part of the ugly phase I get it. But if I can adjust something I am willing to try.

I have turned off my white lights, now only running blues. Shortened the time to 8 hrs @60%. I was feeding twice a day, went down to once a day. Water change every other day, 1 gallon. I added a uv sterilzer a few days ago and added a fresh dose of copepods.

My parameters are in image. I know my alk, cal and mag are low. I am having trouble with them. My alk is now 9.6, but my cal and mag are still low. I have AFR, but only brings my alk up to where it needs to be. Zoas and cloves are all open and doing well.

any advice?

Ah yes. We are going to need better pictures under white light please. Is it stringy or stuck to the rock? If stringy it could be briopis or green hair algae if its on the rock its not much to worry about. Go out and fine some turbo snails and emerald crabs.
