It's time for another bottle of magnesium and I'm wondering -- are some of you brand-loyal (e.g. Red Sea only) or do you go for the best price? If you've tried a few brands, have you found one to be better quality, more accurate, or to have created miracles before your eyes?
Is the dosing the same across the brands? 1mL (in 100L/25g) = 1ppm?
It looks like the best deal on Amazon is a gallon of Fritz ($30). Next cheapest is ESV's gallon ($36), Brightwell's 2L ($25), and Red Sea's 1L ($25).
