What do i choose for magnesium, i am using randy's improved formula. I choose "Randy recipes 1 and 2 versions A and B??"

Havent dosed magnesium before until now since i finally got some magflake from a local reefer, and got a test kit for mg. Tank setup since july. my test kit showing 1200, want to increase to 1350. It says to dose 1300ml, this is correct right??

That's the right line in the calculator. I don't know what the total water volume of the system is, but I'd probably try 1/3 of that dose, and see how it goes. Raising magnesium 100 ppm per day should be safe.
