And you can get a 40L bag of Mount Sylvia Diatomite kitty litter from the pet super store in virginia for $18

Im going to pick up a bag of maidenwell tomorrow

the most commonly used particle sizee is the 2-7mm, 7-15mm is good for adding a coarser component but personally I would only add that on large trees.

cheers
