Calibrated ORP probe 3 times to 400 - Drop in water it goes to 900+. Is there something possibly throwing this off? I don't think its possible to have an ORP that high in saltwater.
I am not running ozone, I run 250 watt UV, carbon, gfo, filter socks, Dual Beckett Pecision Marine XL4 skimmer, and dose Kalkwasser through a doser, not ATO.
Thanks for any thoughts on this. Corals and fish are doing fabulous!!
Temp 78
PH 8.8
Alk 11.2
Nitrate 10
PO4 .06
