TM All for reef high mag?

[Salty_Northerner]

Can someone tell me how much Mag is in 1ml of AFR?

I used the liquid form and now use the powder. I weighed 160g of AFR powder and added it to 900ml of rodi water and mixed it up. I tested mag yesterday and to my surprise it went up from 1400 to 1540??

I use TM pro reef salt and it wasn't till I mixed up the AFR powder that the Mag shot up, Is this even possible?
Im dosing 8ml per day in a WB 35.2 system so about 30 Gallons total.

SG 35.0
pH 8.17
Dkh 8.8
temp 77
nitrate 6.3
phosphate 0.06
Cal 453 to now 465
mag 1540

Test error. Nothing else is possible.

Even if you added powder magnesium chloride hexahydrate, it would take 133 grams to cause that rise.

Thanks Mr Randy that puts my mind at ease.

For reference here is the AFR recipe from way back:

So in 1L of AFR there is 12g of Bio-Magnesium.

From TM site you need 16 scoops of Bio-Magnesium to raise Mg from 1400 to 1540 in 30gal system.

So AFR does have Mg, but per the recipe it is not a source.

Good luck,
