I live in Indiana. We have 6 acres, 3 that is wooded. Lots of limestone here. I have brought lots up to go around my gardens, but I'm sure they have been sprayed with weed killer. But, if I would go get a couple of rocks from the woods and wash them in RO water, could I put a couple in my sump to increase my KH? It seems to be low at 7 and I thought it would be a natural way to raise it.
