The caves have been curing in 10 gallons of water for 2 weeks now and the ph reading was off the charts. My ph readings only go up 8.8, so it was that or higher. My guess is higher. The caves are now in a fresh 10g’s of water with the ph starting at 7.4. I’ll check it again in another 2 weeks or so.

The caves are still soaking in a tub of water. The ph change is still too high.
