Seachem Reef Advantage Magnesium vs. Red Sea Foundation Magnesium B

rsucre · 06/08/2019, 05:43 PM

Hi.

This is not about which product is better. I would like to know how to use Seachem Reef Advantage Magnesium (powder/crystals) to make a solution that is equivalent (or approximately) to Red Sea Foundation Magnesium B.

My 500ml bottle of Red Sea Foundation Magnesium B is empty and I have a 300 gram bottle of Seachem Reef Advantage Magnesium (powder/crystals) available.

Your help is appreciated.

You'd need to use about 70% more by weight, or 40% more by volume, according to this calculator:
