How much BRS magnesium liquid should I dose based on the amount of saturated kalk I am dosing?
mag supplement is BRS for general adjustments-7 1/4 c. Magnesium Chloride : 1/2 c. Magnesium Sulfate to make 1 gallon of solution.
I searched and read a couple threads on this but want to check to be sure I have this right.
I am going to start dosing saturated kalk. I want to add (separately) about the right amount of Mg. I will test Mg periodically but the tests are not super accurate so I’m trying to get the ballpark addition right and I can adjust as needed.
From a previous thread, @Randy Holmes-Farley posted: Magnesium is precipitated (e.g., into coral skeletons or abiotic precipitates) at a very rough rate of about 1.5 ppm magnesium for each 17.5 ppm calcium and 2.8 dKH of alkalinity.
If i dose 500 ml of kalk to 20 gallons of water, hamza’s calculator show I am adding 5.79 ppm Ca and 0.82 dkh Alk. Using the ratio to Ca above I need about 0.5 ppm Mg. Using the BRS calculator that equates to 0.8 ml of Mag supplement.
does that example seem right?
