Unable to locate the correct size of crushed granite for the gritty mix. All I've found locally is 3/8" as shown on the left. Way to large, right?

They DO have have another product much closer in size, shown on the right. It's considered a 'decorative' product. Can I sub this in place of granite? (not sure what specific rock it is.....doesn't appear to be porous.

Price per .5 cu. ft. bag
3/8" crushed granite $6
'decorative' product on right $19 (OUCH!)

No Gran-I-Grit could be located, and poultry growers grit found is way too pricey ($13.99 / 7 lb. bag)
