^^ So true. I also use bulk salts, and also mix Magnesiums too for the more balanced product. The savings are INCREDIBLE! Same goes for Calcium and Alkalinity.

To get the exact ratio in NSW it's something like 9:1 mag chloride to mag sulfate. A lot of people just use mag chloride for that reason, but epsom salt is pretty cheap so I always add it.
