Probe placement

[jporter17]

I will be locating all four of my probes in a GHL measurement cell. Should there be a problem with it measuring after a UV sterilizer and just prior to a chaeto reactor? Will the UV add enough heat to concern me, or alter the ORP, PH, or Salinity readings? Should I try and locate it immediately exiting the sump and prior to the UV? Thanks. JP

I put mine in the skimmer chamber of the sump. or as you stated put the probes in the return.
