You can certainly use the Mag sulfate you have. Epsom salt is another form and may be what you have. As far as your nitrates did you see what plantbrain said? I can count on one hand the people I would blindly follow advise from. He's on that list! He devised the EI system. He happens to be one of the most knowledgeable people on earth when it comes to planted tanks. Did you understand what he meant by using K2SO4 (potassium sulfate)?
