Do you have any pictures of it?Just wanted to add my experience with the battle. I dosed mine over a month ago and it made a dent in it, I have about 75 gallons give or take I started with 1300 mg, and after three weeks when that didn't work, I added the the rest of the 10 pack I got. After a month it is still lighter then it used to be but still there. I think that it is turf algae and maybe doesn't work as well with that. I ordered some Vibrant that should be here today, hopefully that will be the magic ingredient. Fingers crossed.
Well..No snail or urchin deaths so far. There have been a couple people that have urchins and not noticed any harm to them.
Thanks for the info and sorry for the urchins but was your treatment worth it in the end?Well..
Got three urchins..
Two Halloween style
One pincusison
14days in.. Algae died off.. Pincushion alive.. Everything perfect but both Halloween died on the same night.. Perfectly active before.. Could be coincidence who know
Yes, It's sad and thanks for posting your findings.It was Yeah but sad if it's what ended them not sure what happened had them a while but to die together seemed strange

Strange isn't it.. I've monitored nutrients etc all been OK to be honest.. My marine pure blocks etc kept it in check could have been anything but just seemed weird. Glad the treatment has worked though.. Was for Gha for meI have 6 urchins that were in the tank when I did the treatment.

I am not saying your treatment did not kill them because every tank is different. I am just sharing my experience.
It is strange. Over the years I have had negative things happen in my tanks that I could never pinpoint the cause. One of the joys(?) of reefkeeping.Strange isn't it..

I found a dead narsarius (spelling) yesterday, removed it as dont want it leaching back into the tank, I just tossed it into the bucket I keep my glass cleaner etc in, forgot about it until I came home from work today and it reeked really bad lol. Whether its because of the treatment who knows, but I also lost a couple of small acans over the last few days tooNo snail or urchin deaths so far.

Sounds like they had a The Notebook moment.It was Yeah but sad if it's what ended them not sure what happened had them a while but to die together seemed strange
I only have a few acans but they didn't react at all during treatment. There may end up being contributing factors that we don't know about that will come out as more research is done. Hopefully you don't lose anything else.
