Hi, I have been using the two parts recipe Alk and Calc for the last four months. The tank has been up and running for two years and I have made water changes twice a month using Aquavitro salt. Never added magnesium. My Mag is at 1120, measured with Salifert test. Apart from the Mag stock solution that must be added to keep sulfates balance, can I use the two parts magnesium recipe 7 1/4 Mag Flake and 3/4 Epsom salt? Will It cause an imbalance and should i use the same amount of Alk and Calc I'm dosing dalily? Thanks everybody in advance!!!
