Well, I am glad I tested these rocks before using them. Last Thursday I brought them into the house, emptied the water and refilled from the tap. Checked the pH and it was 6.0 or lower on the API kit.
I tested it again yesterday and it was 7.4 on the API kit. In 4 days the pH had swung from one end of the scale to the other. I am a little dissapointed that I can't use them, but glad I took the time to test them out first.
