Algae I.D./help!!!

[nerdz]

Hi,

This algae is on its way to taking over my reef.

Anyone know what it is? The closest thing I could find was "Caulacanthus ustulatus" on Melves Reef I.D. page, but no info...

I have a 37g mixed reef w/ 20g sump. Running biopellets for ~1 year, Vertex 100 skimmer, 250w MH w/ new 14k bulb.

phosphates are low"ish", I dont have low reading test kit. I don't suffer from much other algae.

I can manually pull it out, (well not really, I have 2 broken hands and a separated shoulder right now from my other hobby ...).

Are seahares strictly hair algae eaters?

Can anyone recommend a CUC and/or fish to snack on this?

THANKS FOR ANY HELP!!!
