For the past two months I've been dosing AquaVitro Ions as needed to maintain my mag levels. Prior to that I was using the standard Seachem mag crystals in combination with weekly water changes to maintain a 1300-1350ppm reading which constantly seemed to fall.
As soon as I began dosing AquaVitro Ions, my mag levels have sat at 1350 without much if any fluctuation. I know the AquaVitro line is new and most of you probably stick to the crystals but in my personal experience, the AquaVitro line is the way to go for raising/maintaining magnesium.
If anybody else has had a similar experience I would love to hear about it.
