no personal experience with epsom.. so i cant tell ya my experiences... just what i have read
Not to spite what you have read (Randy knows his stuff dealing with chemistry) but I have used store bought Epsom salts for over 3 years and have never had a problem with the Calc and Alk being antagonistic. IME I have never had a problem with sand clumping or cementing, nor have I noticed an increase in PO4's. I have maintained good coralline algae growth and respectfully, good coral growth. Some might not feel comfortable using it, but for me, it works like a charm.
Like I always say, everyone else’s mileage may vary, and probably will... Whatever works for you, go for it!
Question: Why don't saltwater manufactures list ingredients along the side of the bottle? My take is that if we all knew what they placed into the bottle, we as hobbyist could easily/or try to replicate the same concoction for much less, with store/local pharmaceutical bought products. This is just IMHO...

how much epson salt raises x gallons by y ppm?
(like baking soda... 1 teas raises 50gal by 1 dkh)
To increase the magnesium concentration by 100 ppm, add 1 gram of Epsom Salt per liter of water.
1 gram = .035 ounce: roughly 1/28th of an ounce
1 teaspoon = 100 grams
100 grams = 3.5 ounces
1 liter = 1.06 quarts: roughly 1/4th of a gallon (0.26)
1 Gallon = 3.8 liters
So, to bring up the Magnesium level 100 ppm in a standard 55 gallon system, we must multiply 3.8 liters by 55 gallons = 209.0 liters. So you will need to add 209 grams of epsom salts or roughly 7.046 ounces to bring up your system 100 ppm. (in layman terms, 2 healthy teaspoons per 55 gallons/100ppm of Mg)
If the increase required is more than 200 ppm then consider doing the increase in several steps over several days.
Of course to get the exact measurement of volume, you'll have to add all components involved. (sump/skimmer/refugium volume vs. actual displacement of rock and coral)
for your future reference
