I was reading that quite a few reefers are using Pavestone Pulverized Limestone as a substrate. My HD doesn't carry that, but they did have "Soil Dr granular limestone". It's intended purpose is a soil additive. I did the vinegar test and it foamed/dissolved. It is also a nice sugar sand size AND pure white. Has anybody used this product? It's less than $4 for a 40# bag. Cheap=Good
