Limestone as media?

I posted this here from a post I had on tropical play sand.
RC member said about limestone also to us.
I put this post now for persons who uses limestone what brands you use?
Also pulverized and pelletized works for you?

There are many here around the Dallas Tx area using the Pavestone brand Pulverized limestone as a substrait. I am using 150 lbs of it in my 125 and I like it. It only cost $4.95 a 50 lb bag.
It is very dusty and required a lot of rinsing but other then that it is pretty good.
