One of the things that changed from a few years back to now, is the improved Calc / Alk recipe
With the updated two part, you now get Mag, and the sodium hydroxide (Alk part) which is LYE has higher PH. What I also like about the new Alk part is it's less cloudy then sodium carbonate (baked baking soda)

I doubled the recipe. Since I don't have many corals my dosage is 23ml of each per day.
