Raising mg

[Proteus]

I'm hoping I find a sweet spot. But it seems seachem a calc may be out. I dosed half of what it recommended and ended up with 1400 ppm


This is from a artical in reef keeping


All magnesium supplements are fairly dilute with respect to magnesium itself, and it often takes surprisingly large amounts of additives to boost magnesium in reef aquaria. For a large aquarium (100 gallons) requiring a substantial boost in magnesium (200 ppm), the amount of supplement may seem incredible (taking, for example, two liters of typical liquid commercial magnesium supplements).
