Bryopsis not dieing with raised Mag

[cmantis]

So for the past 2-3 weeks I have had my mag at 1800-1900 in the hopes of killing off some nuisance algae including bryopsis however besides for one patch it doesn't seem to be affected. This is using Kent Tech-M btw.

For some reason, it doesn't work for everyone, at least it didn't work when I tried it a while back.
I even had the levels up to 2100 ppm and made sure that I stopped all carbon filtration and nada.

Yeh I took my reactors and skimmer offline. What to try next I have tried turbos, lettuce nudis and blunt end sea hares

Here is the kicker. I have two identical tanks with identical equipment (pumps lights etc) plumbed into the same sump and only one has this problem the other is clean as can be.

Bad rocks? Pull em out and cook them. They are acting like an ATS foe you right now..

 

[cmantis]

Same rocks in both tanks and no nuisance algae at the beginning this is recent. Probably came on a frag.

 

[lnevo]

What i meant was take out the rocks that have it now...

it has to be the kent tech m to work

Read first post thats what im using.

Take the rock out, even if you have to kill anything that is attached to the rock. You can also try to cover it, take a tile or something and put it on top of the effected area for a few weeks. How bad is it?

i got same problem b4, i keep Mg up, almost kill my coco worms (2) i replace the 3.500 K (warm white, LEDs) then no more.

 

[cmantis]

Its not the lights though same exact setup and this is only in one tank.

The other tank:

Both (so you can see what I mean by they are identical except for the algae):

Is it maybe a fish or invert in your second tank that loves the nuiscance algea?? Your purple is def a difference and cld have a taste for it. I wld think nutrient control could help what kind of skimmer you using. I had good luck with carbon dosing but could also try lanthanum chloride, that was next on my list to try if carbon failed. Could also pull the rock out and shoot it with hydrogen peroxide. Did that to a few pieces that i could remove easy and works awsome. Read you could also dose it on other forums but i didnt try it. Btw love the male anthia he looks awsome.

Same inverts in both tanks. Same CUC and when I tried lettuce nudis and sea hares equal in both tanks. Ha if that tang could clean it up hes gonna taking the elevator up top.

 

[Yani1133]

Haha thats my shot in the dark my kole likes some algeas, its crazy its in one like that and not the other.

 

[cmantis]

Actually not a bad idea think I will get a kole always wanted one. I just have to make it back down to NJ though.

 

[polywise]

that's a weird situation with both tanks on the same system.

thinking out of the box a bit -- the tank with the issue is the one with most of the fish. I assume you feed that one the most, right? do you think it is from the food you are feeding, possibly a bit too much in that tank?

 

[oh207]

Which tank has the algae, top or bottom? And is it exposed to extra sunlight during the day?
I noticed that in my tank where sunlight hits there are all sorts of weird stuff growing.

I found no invert or fish that would touch bryopsis. When the Tech-M did not work for me on two separate dosing attempts, I resorted to manually pulling each rock out and rinsing/scrubbing under the sink. This did not keep up with the growth so after 6+ months, I pulled all my inverts and corals out into a temporary QT tank and hypo'd the system. That actually worked but it took over a month and I would not recommend it unless it's a last resort.
