Weird stringy algae on zoas

[fatarw05]

Hi everyone. I’ve had this zoas for a few months now and I cannot get this algae(?) off of them. The zoas keep closing up when it grows too far. Anyway I can get rid of it? A harsh scrub? Or dip it?

I can't really see anything, but if it is algae I would do a 1:10 hydrogen peroxide to tank water dip for 5-10 minutes. But I am unsure if it is algae because I cannot see it very well

Do you run a refugium? It looks like strands of Chaetomorpha.

Diluted hydrogen peroxide dip. The Zoanthids may look mad for a day or so but the algae will be gone.
