Hair algae won’t go away

[TokenReefer]

I just made a snail only ( cleaner pack purchase at @reefcleaners. Cerith, mini cerith, nassarius and nerites. I have some persistent gha and my cuc seems to be on vacation lately. I need to refresh them. I can't find cerith locally and my hermits wiped out all but one; I like ceriths. One reason I ordered. The prices just can't be beat is another. Water parameters are fine so I'm throwing more mouths at the issue. We shall see
