I hadn't looked at the profiles for the fish that you have in the tank until now... well, the highest pH fish is 7.5, the Oto Catfish... and even that is the high end of their range. I'm honestly not sure how much of a factor that is but I am sure that it has long term implications, just not sure how much of a problem a 0.4pH shift is if you are already out of range, although I know for certain it is less of a concern than the ammonia and nitrite are.
You might want to consider lowering the tank temp to maybe 76F... the cory's are probably not great in the 79 range long term. With your fish mix, 76F is about optimal to try to keep everyone happy... even a tad low for the loaches at that. This is one of the may reasons I went with the catfish I've chosen, higher temperature range fish overall. Cory's were too restricting for me.
