Something is up with the Apex's ph probe, since I pulled it out to test the freshly mixed saltwater its only reading 7.2 on the tank when before it was reading 8ph. Maybe some oil from my hand got on the end of the probe?
I found a really old API ph test kit and test my display, the freshly mixed salt, and my ro.
According to the old API test my RO is around 7.4, the new salt is around 7.9 and my current tank water is around 8.
