how to get red algae out of sump/chaeto?

I have some red algae (not cyno) on my chaeto in my sump, and I can't figure out how to completely get rid of it. For now, I deal with it, and I manually remove it when it becomes an issue.

I've left the lights off for days, the algae diminishes, but when I turn the lights back on , it slowly starts growing again.

Besides the usual water changes, is there something I could do to completely get rid of it?


I was thinking of running the chaeto through freshwater in the hopes that the algae would die off before the chaeto... Would this work?

Thank you

i wouldnt do it, i know cheato can survive a quick rinse but if somehow it gets stressed cant it go sexual? then youre in big trouble.
i wonder how coral dips would affect it?

from my understanding (and I may be wrong) but I thought Chaeto doesn't go sexual, which is one of the reasons people use chaeto rather than caleurpa.
