So I just purchased the ingredients to make the brs Magnesium formula. I use i.o. reef crystals already and it has a healthy initial dose of mg, cal, alk. Instead of doing the 20oz initial dose. Does anyone know what the recipe is for reg dosing. i.e. 2 oz per 50 gallons = 50 ppm of mag Any help is appreciated. If it helps I have a 75 gal tank with sps. lps and zoas. 100lbs lr and 50 lbs of sand. Total water volume is around 50 gal I think
