Keep all lights off for 2 days - no extra light in room too if you can help. I'd also do a good size water change. They have small energy reserves and you will get most of them if they are deprived of light for that long - your corals should be ok.
I had the lights off for a total of 36 hours and today when the lights came back on my girlfriend called me and said those SOB's are still there!
ARGHHH@$%#%$#$%!%^!@#@!
Granted, I was told they were reduced probably by roughly 50 percent but still there none the less. What else can I do to battle these Arseholes?
No phosphates in my tank. I use RO/DI water with 0-1 tds reading. I definately do not overfeed. Refugium on the way for macro algaes. What else can I do?
I was able to get rid of dino out of a 20 gal by using feather calurpa. Been a few years but seems like I left the lights out for around a week and didn't work. The calurpa did the trick pretty quick. Only problem was the calupra then took over the tank. But with a lot of scrubbing, picking it off the rocks with tweezers and a couple of sally lightfoot crabs I took care of that problem. Now it's totally full of xenia.
My suggestion... wait till ya setup the refugium and it should help quite a bit.
I'm also having the same problem in my 75. Tonight I vaccumed the top layer of the sand bed to get a lot of the maroon scum outa there and did a water change. I'm upping the CaOH dosage and my lights are now off.
While doing research, I found something Len said....

There are chemicals that can kill dinoflagellates, but I don't recommend them since zooxanthallae (the symbiotic algae in corals) are dinoflagellates.
Do these actually work any good? I got a mushroom rock in my tank but I could temporarily move it to my bro's 20 gal. during treatment. Anyone know a specific product and maybe where to get it? Thanks a lot!
I will restart my lights tomorrow morning after 60 hours of no light!! If Ipray that I will not see *&^T(*&## again but if they come back I will post pictures for you...@@#$$#$!&#$
420 - sorry that it didnt work the first time - I did a full 48 hours and kept all lights off in the room per advice I got from a RC member. Immediately at end of cycle I did a 40 gallon (15%) water change and cranked up my skimmer to run very wet. I had a small recurrence a few weeks later but that quickly subsided and I am now dino free.
Chemi clean will supposedly work also - I think it's an oxidizing agent. I am leery of dosing anything in my display like that however.
I tried chemi-clean but it only killed a small amount and then it came back in full force.
I turned the lights back on today after 50 hours of TOTAL darkness. After only 4 hours of light I can now see that there already starting to come back in a very small amount.
Im running RO/DI water right now for a second 10 gallon watter change on a 55gallon tank within 24 hours.
I Don't know what else I can do other than get some macro up and running in my newly bought aquafuge.
I am just starting up a new tank after being out of the hobby for a year. I have something similiar on pretty much everything in the tank, however, mine is not that dense. Right now its looks like a thin, brown, hair like algae creating lots of air bubbles. It is easily blown off rock with a baster. I am using tap water (I know, I know) and am pretty sure that is the culprit. I should have DI water pretty soon for topping off. I will try and get a picture of mine to post here tonight.
