Some pH buffers, like SeaChem Marine Buffer, have a fair amount of boron in the form of borate, which will raise pH a bit. It's possible that the reading is in error, as well. Testing for boron is difficult. A 10% water change will lower the reading only by 10% in the very best case, and possibly not at all if the salt mix has excessive boron.
