Lesco is the first place to look. 50 pound bag tends to run about $15.
its also sold some times under the name Oil-Dri. one person said they found it under another name at one of their local auto part shops i think it was auto zone.
thanks for the info . . . I like the AquariumPlants product, but if SMS is the same stuff, I'll keep an eye out for it . . .
to the OP, if you want to go that route, try www.lesco.com; they have a web presence, and they also have a store locator. they do have stores in Michigan
