Have you beat Bryopsis with Kent Tech M?

Looks like to me. I found using peroxide works, but I have several corals that get really ****ed and lose all their color for 2 months. So not really an intank option for me. I did remove one rock, dose peroxide, rinse and put back, that did the job for that rock.

Ditto on having it work in the past for killing algae, like you I don't find all corals tolerate its use. Peroxide does a great job of killing pest nudis as well, better than revive IME. 6 months ago I dosed the whole tank with 29% h2o2, I think 2 or 3 mls per day in 55 gallons. Not sure what I was really expecting to happen but all I got was air bubbles everywhere, it looked annoying so it went offline after 10 days.

I have about 50mls of Tech M left on the doser right now, when that finishes I'll be switching back to Shlobster and letting it fall back down to normal levels. Over it for now. Gonna blast this patch with some 3% for now and see what happens

I tried a letuce nudi in the past. Lasted 10 minutes in the tank before being sucked into a pump. Didn't stand a chance in a high flow sps tank.

Forgot to reply to don.ald about that. Tried a lettuce nudi a while ago. It did an awesome job of getting rid of the algae, or so I thought. When it ran out of Bryopsis to eat it withered away and disappeared, pressumably died. It lived for about 3 weeks. Once it was gone. The algae just came back in the same spots, I assume they leave little bits of the base behind which will regrow.
The same goes for other nudis I assume, Berghias, Monti eating ones etc... no more food, they die...

Had it in my tank awhile back. Freaking nightmare to deal with. I also tried Kent Magnesium Tech M and had some doubt like you do. So I poured some of it on the Bryopsis just to test the theory. It practically melted away. Anyway, it worked just take sometimes. Good luck.

Does it grow from runners? If so could it be feather caulerpa?

Haven't seen any runners. There's a few single strands that appear to grow from nothing. The photos I've seen of Caulerpa make it look like its a bit rubbery, is it? This stuff I have is very feathery

Just read on Wikipedia that Lettuce nudis arent actually nudis, not even related. They're Lettuce sea slugs (Elysia crispata)

Hmm so spot treatment with Tech M? Could give that a try
