Need some advice with Kent Tech M

[Auston]

Hey there. so I've done some reading and many people have had success using Kent Tech M for the fight against bryopsis. I tested my tank for magnesium today with the my new test kit and I had the sad resut of 1000ppm mag. Several sources say to raise the concentration no more then 22ppm per day.

So at that rate it will take almost a month just to get the levels up to standard sea water levels 1350-1450, and another 3 weeks to get it to the levels that kill bryopsis.

My questions are:

How much can you raise the magnesium per day without ill effects?

Does anyone have a success story of this and the dosing numbers you used?

I've heard of snails and inverts dying from this method, is this common? And common or not is this caused by poor execution of the treatment? (Not maintaining proper buffer)

I'm going through this right now , you can raise it safely up to 100 ppm a day .

You usually have to raise it around 1900 to 2000 . Although it's not the actual mag that kills the bryopsis but some sort of heavy metal in the solution.

I agree 100ppm per day is fine.
It is not the actual elevated level of mag that does this, but the amount of Tech M, so really you may not hit the upper levels of mag before seeing bryopsis sluff off, the fact your mag is already low may actually benefit you.
I would be shooting for 1700-1800 and I bet you will begin seeing results before you even get that high.
I don't believe it is a heavy metal, but an impurity of some sort due to kents processing of mag, though that is still somewhat unknown as to what that actually is.
