Toxic Alage?? or Good Alage

[saltyrockbox]

I have an overflow that is full of growing algae and was wondering if it might be harmful or retard coral growth. I know that a few species will release toxins, I don't think this is that type. But here is photo maybe someone can identify the species for me.

The over flow works like a refugium, there are a few pods in there and this algae that I can scoop out once an a while...for nutrient export.

I was covering the top of the overflow to block direct light but I think if this is a safe algae maybe I should help to grow and use it like you would use a macro algae species...

also the fish seem to like eating this algae when I clean out the over flows.
