Whoa just tested the pond again figuring maybe after the last super heavy rain the pH would have possibly dropped, nope. It is up to 8.7 now! I've never had a pH above 8.3 and that was once. Heavy rains must have brought some crap with them or a very unlikely possibility is that it flooded over there and something got washed into the pond but that is so unlikely cause it is graded properly and that entire section of yard is raised. So the pond is getting a water change now! lol I am on a well though so I hope my source water isn't messed up too. It tested it's usual 7.6 pH but that before outgassing.
