My ph reading is at 6.3 all the way down from 8.3 yesterday. I didn't change anything to my tank in this time. My orp reading is at 512 which it usually sits at 450. I will check my probe but i recalibrated it about one month ago so it should be fine. All my livestock looks normal. Would everything die at that level?

Unless you massively overdosed a CO2 reactor, that pH measurement is definitely not accurate.
I'd recalibrate now. One should never assume that a wild reading like that that is on a meter calibrated a month ago is accurate. :)
Some meters, like the Pinpoint, can suffer interference from certain lighting ballasts, so be sure it isn't that by measuring pH in a cup of water away from the tank. :)

as always thank you Randy. I figured it has to be an error. It happened after i recalibrated my salinity monitor on RKE. Which after 5 recalbs i still can't get the thing to work right.

OK, maybe you accidently messed up the pH calibration.
Sorry, I've not used an RKE to help with that.
