A few of my zoas have been getting a brown film like algae in them. Every night I have been blowing them off with a turkey blaster in hopes they open up and nothing. I moved them to a higher flow area to see if the powerhead would help and I have seen no progress.
Any other ideas? I have a decent sized colony on a rock that I don’t want to lose.
