Review on 🐠 Reef Advantage Magnesium: Premium 1.2 kg / 2.6 lbs Supplement for Optimal Aquatic Health by Cheska Perry

I dose Sechem Reef Advantage Magnesium in my aquarium. I got back the amount I needed to increase my magnesium a bit. For example, I increase the Magnum from 1200ppm to 1375ppm, my 120 gallon system takes almost a pound. Indeed, here is the entire contents of this jar. I think next time I'll order an even bigger can. You can find a handy Seachem product dosage calculator if you do a google search for JDieck Reef Chemistry Calculator FV.
