This is probably a dumb question but I'll ask anyway. I was planning on putting a limestone border around my pond to control some erosion problems I'm having and also to trap mulched up debris that washes into the pond when it rains. I was explaining this to a friend and he told me that if I do that the limestone may change the PH level of my water. I didn't think it would, but now that the thought is there, I have to ask. Will the limestone affect the PH of the water? Right the PH is 7.5
