Hi mavgi,
Okay, I might just have to go a head and get the bead type sulfur then . premiumaquatics is selling a 3.5lb for $55.89

I'll be using my old geo calcium reactor and convert that to a sulfur denitrator. The chamber on this reactor is about 6" dia and about 24" high. How many pounds of sulfur and arm or gen-x media should fit in this reactor?
