I just purchased my first container of Aquaforest reef salt. I've had problems with my current salt driving my alkalinity too high. From what I've been able to research Aquaforest comes in at a lower number. I'd rather dose up then have an alkalinity spike and lose my SPS's. If this goes well, then I'll look to moving into the rest of the program. Currently, I'm dosing with ESV ALK,Ca, and Mg.
