I think I've FINALLY found a descent product for Al's gritty mix. Got the clue from the San Diego Bonsai Society. Located it at a roofing supply store. It's 'A-1 Products Granite Roofing Granules / Poultry Grit #5' from SG Wholesale Roofing Supply Inc., Lemon Grove, CA. (hop, skip, and a jump from San Diego) 80 lb bag (7/8 cu. ft.) for $7. I liked the $0.09 per pound price!

Not sure if I should further screen to size????
