New pond high PH Mosquitoes and dying goldfish - HELP

[craigvee]

Did you try the vinegar test on any of that stone?

No, can you tell me more?

I'm guessing the test is to determine whether the rocks has a high component of limestone.
As for my fish comment, I didn't imply it was causing the spike, but there's no reason to continue adding fish till you get the water quality figured out. Hope you get this figured out soon.

This may be an annoying solution but I would suggest doing 3-4 total water changes and see the PH a day after the last water change. If the ph rises after the last water change then you have a substance leak problem for sure.
