I have a large number of 1.5 inch frag discs for sale. These are totally cured and ready to use. I have used hundreds in my frag tanks and they work great. 45 discs for $12 shipped.

Close, made out of calcium hydroxide. When it reacts with water it turns into calcium carbonate. No harmful additives like you might find in some concrete mixes.
