Hey Guys,
I bought a new ph probe from bulk reef supply to replace the old one I had and the cal seems off. While setting it up in 7 buffer it showed 6.93 and in 10 showed 9.75. Now in the tank it’s reading low. Not sure if I should let the probe do its thing for a couple of days and re-cal it or try now.
