Killing Bryopsis with elevated Mg levels.

I doubt Cl will have much effect vs SO4.
Mg is quite another matter.
There's some speculation, that high Mg may be able to stunt some species of plants.

But, doing this and the impacts on other macros might need to be addressed. Basically, how selective is it for Byropsis is the question that needs posed as well.

Might be okay, stunt the noxious algae, but no harm relatively to the corals or other desirable macros.

Getting somewhere in the long term should be a goal to resolve of noxious algae, not just a short term guess and hoping it works.

A better understanding allows a lot more utility.

It might work, I dunno, but without some confirmation, you really cannot say. Same deal with the MgCl2 vs MgSO4.
You can test to Cl vs SO4 effects for that also.

Something happened, but what specifically and why are quite different than just the observation. It's just a one time correlation at this point.

Since folks state that they can get rid of it this way, take some from another tank and add it, let it infest well, then try this method again, repeat several times.

Since, if you are confident of this control method, you can get rid of it after an infestation easy with this method as claimed.

Are you willing to testthe theory?
You should be if you feel strongly about things.

I do not have any Byropysis to kill right now :(
I'd try it otherwise.

You need to be able to induce Byropsis and or have a starter culture on hand and be able to grow it consistently(generally not hard for many with an infestation) to test several things like this.

Still, if the method works, then getting rid of it should not be an issue, why do not more try this?

They are not interesting in testing their tanks, unless they have no other choice and rarely if ever repeat noxious algae test on purpose. That's just not their goal, so we end up with little testing, lots of speculation.

If you feel strong about the method, and confident it works, it should be repeatable.

Showing algae control methods vs just having a nice a tank are two different goals though.
