It's been a while since I mixed a batch of Mg for dosing. I have 5 gallon buckets of powder Mg Sulfate and powder Mg Chloride from BRS. When I opened the powder Mg Chloride bucket I discovered that the top layer is liquid. I imagine it's safe to use but I wonder if I should change the mixing ratio from the BRS recommended formula (3 cups powdered Mg Sulfate with 5 cups powdered Mg Chloride per gallon). I'm thinking that 1 cup of Mg chloride powder does not have the same concentration as 1 cup of liquified Mg chloride "powder". Thoughts?
Mg Powder Mix Ratio when Mg Chloride Powder has Started to Liquify

Thanks. I neglected to state that I had previously opened the powder Mg Chloride bucket and used it in its powder state, well over a year ago. I store the bucket it in the basement where it is humid in the summertime. The BRS seals are not that great in my opinion. I think that humidity from the air is what caused it to liquify, but I am not a chemist either and I know nothing about the chemical reactions that may have occurred.

deliquescence, meaning that it attracts moisture from the air to the extent that the solid turns into a liquid.
There is no way that I found to determine the strength of the solution formed to mix it up.

I stored mag in our damp basement and it turned into a vat of goo as well. I didn't use it, assuming the chemical reaction to liquify it ruined it, but apparently it is still good to use. I would avoid doing so if the container had any gunk in it.
