I've used the esv for years and it is now getting impossible to get. I have plenty of calcium and mag. but low on alk. What would a good replacement be? I have some Reef Builder that says it raises carbonate alkalinity but it is a powder and I want to dose it with the doser. So if not this, what is a good replacement for esv
