GHL probe/dozer line placement

[bugzy]

Hello all. Looking for any tips or best practices for probe placement along with where to dose in my sump. Should I be taking measurement and dosing in the refugium area or have all of the probes/dozer lines go into the return section.
Appreciate the help!0

I have mine after the filter socks, in the shade with a powerhead directed at them.
Dosing lines are in the return chamber. That works for me.

Hi, can the sensor go submerged? Because when my feed pause is activated my return stops and the sump water level increases. It will definitely then cover my sensor at the top to make it submerged:(

It ok to have the sensors temporarily covered in water it has happen to mine in the sump and no issue. My dosing lines are in the return pump section of my sump and my water senaors and probes are in be media chamber prior to the return pump.
