Cool. My granite tip made it in there. The proper term is decomposed granite. Not crushed granite.
I can confirm the high alkalinity of limestone. After filling my pool with well
water it took 18 gallons of muriatic acid to get it in balance!
When out of staters first see the seashells in the limestone they are dumfounded. We are 300 miles inland.
I did not know marble was a compressed limestone.
