I was at Kroger's today and getting Epsom salt. I found something interesting and thought I would ask. They sell magnesium supplements which I saw was magnesium oxide. My question, why wouldn't we add this instead of Epsom salt which is magnesium sulfide? Wouldn't the magnesium oxide be better for the tank?
