which mag is better for raising levels. chloride or sulfate. Casey said:Its best to use the combination of the two. Farley did a write up on it and goes in much detail about balancing the chlorides with the sulfates. It was the basis of two-part recipe he came up with.
Don't be alarmed by the volume of the mix you need to add to get even a 100ppm rise, it can be quite a bit.

so i can mix equal parts of the two? Is weight an accurate way of making a mixture of these two. thanks for the article man this new baby keeps me up. said:No they go 5 cups of chloride and 3 cups of sulphate and fill RO/DI water to mix a gallon. Shake it well, stir etc. It will end up a bit thick and you may have sediment at the bottom so just shake before you dose it.
