Finally an easy solution to bryopsis!
- Thread starter TWallace
- Start date
Two weeks and several gallons of Tech-M later, the ends of the Byropsis are lighter in color, but still not dying as I had hoped... Manual removal this morning with a scraper and siphon hose. Hopefully it will not come back...
We'll see.

It's only been a few weeks, but there is no sign of a reappearance in my reef.
It took less than a week to kill it all.
well, I read through this thread and decided to give Kent Tech M a try. I had been using MgS04 mixed with MgCl in a 3:2 ratio and drove my Mg up from 1200 to 1800 for several weeks with no effect on the Bryopsis. I then switched to Kent Tech M and had to go up to 2200 before the Bryopsis started to turn brown and then grey, but only in certain areas, other spots have been very slow to die and there are other areas still growing, though much slower. So, I've gone up to 2400 with Kent and still getting very slow die off and slow growth in other spots. I'm going through a lot of Kent, about a gallon a day for my 560g system. Interestingly it appears the areas of greatest die off are closest to the lights, I'm guessing the toxic ingredient in Tech M gets taken up during the growth phase.
I'm wondering, since the bryopsis is 99% in my display what do you guys think of turning off my return pump, keeping my CL running and just treating the display? How long should I leave it before turning the sump back on? I'm getting tired of spending $30/day. And how high do you think I can go? So far I've lost my serpent stars but everything else looks fine. Would you continue to push it up even higher? This has really got my goat!
phosphates 0.05 on Hanna meter
nitrates 0 on Siefert

yeeeesh.... I'd HATE to fight that stuff in a 500g system.
Just how much volume does your sump hold?
I'm just not sure if it would be a good idea to remove items from the tank system that will help them deal with the stress of the high mag (and whatever is in Tech M that kills bryo). If your organic pollutants go any higher, since your skimmer and any chemical media you have will be offline, you may stress the corals way more than necessary.
In your situation I'd not dose much more Tech M until some of that water can be removed. Unfortunately you did the same thing I did and tried mag sulfate/chloride (which didn't work, exact same result as when I tried it). Now the mag is WAY high and you only have a little room for Tech M before really getting the magnesium to an unsafe level.
I'd recommend doing some water changes, but boost the NEW water up to around 2200 with the Tech M.... but don't add any more Tech M directly to the existing tank water until you've replace a large portion of your water, I'm guessing 30-50%, over the course of a week or two.
Man, that's a lot of water though!

Someone on this thread reported tolerance to tech M when it returned after the initial treatment, my concern is backing off and allowing the bryopsis to develop resistance
However I share your concern regarding over stressing the corals.
Has anyone had luck with a rabbit fish?
Ha-ha yes, but we're also going through Tech M by the gallon! :thumbsup:
Quick question, How are you measuring beyond 1500ppm? I have the Salifert kit and that's as high as it goes. Are you doing a dilution or refilling the dropper syringe?
I'm refilling the dropper syringe

Has anyone noticed that the longer this thread gets the higher the price of Tech M gets?

Lol, actually I was thinking something similar the other day. It's like $6 a gallon more than it was 6 months ago from the same places I bought from 6 months ago.
Since it all grew back, I am resorting to Tech M ONLY ONLY as a last resort now..... but even then I suspect it would come back again.

I had a magnificent foxface in my tank... it wouldn't touch the bryopsis
At first I raised my Mg by 300 ppm with Seachem's Reef Advantage Magnesium, with no effect. Then I raised my SO4 from 2700ppm to 4500ppm (with Na2SO4), this also had little effect on the Bryopsis. I let my levels come back to normal value's over a few weeks time and then I used Kent Tech M to raise my Mg 25 ppm a day. Within one day some parts of the Bryopsis turned gray and within one week almost everything was gone. The few pieces that were still present were brown and easily removable.
Here you can see how terrible it was.

Thanks for the post, Steks. Fairly clear evidence that the effect is an impurity in Tech M. 
It's interesting that you let the Mg fall back to normal prior to using the Tech M. I used MgCl and MgS04 with no effect on Bryopsis, then immediately switched to Tech M, it's dying off but rather slowly, and using a boat load of Tech M, I wonder if I had let the Mg normalize prior to treating with Tech M if I would have had better results. My Mg is now at 3500, aside from loosing my serpent stars and RBTA's closed up but not dead all other coral and fish seem fine. I removed the RBTA's. For me, it was either kill the Bryopsis or quit! :lol:
lukinrats, that is exactly what I got in the tank.
I posted this in my tank thread, but I don't guess many people are really interested in replying to that thread... it is here , but I wanted to put my pictures in this thread to see if I can get an opinion
Here are the pictures... Tell me whether you guys think it is Bryopsis, and if it is, should I use the Elevated Magnesium treatment?
The worst spot of it is in that first picture, on a piece of Marshall's Island rock I have... It is the only one in there, and has never been able to grow any coralline, so that is where NA usually starts
Thanks,
Nathan
It scrubs off pretty easily with a toothbrush, but even then there will still be some left... Also, if you scrub it down, it will come back... The only strange thing to me is that it will only grow to the lengths you see (so far)... Now, I call it strange, because I have never dealt with it... It may actually be typical
That's why I am hoping you guys can give some clues
