I personaly have decided to go with sugar sand as I did a month long test on about one pound of each substrate and I wan't totaly happy with the amount the lime compacted. it might be harmless but it was a little to hard for my liking. having said that this is the sheet for mighty white dolomite.. I am not sure what brand you posted Shadetree, maby generic?
