Cannot kill off Ulva, it always grows back.

[TheSheff]

Hello, I have been dealing with ulva in my DT for a couple of months now, and I cannot seem to get rid of it. I have a tang, snails, and emerald crabs. None of them seem to want to eat it. Does anyone have any other solutions?

Do you have pictures under white light of the Ulva?

I've been fighting it for a year. Found that fluconazole will kill it/slow it down, but it just comes back. If you find something that solves the problem please report back.

How big is the tank? An urchin will eat it. I am sure tangs and rabbitfish/foxface will eat it too if the tank is large enough

I have a tang in it right now. Controversial but it’s a 40 gallon so I can’t get that many fish in there. I have an urchin but I guess I could try getting another .

I will definitely let you know, it’s so annoying, it grows so fast and always comes back
