Hello everyone !
I connected my new GHL Profilux 4 to my tank.
The tank started cycle 6 days ago , the P4 was connected 2 days ago.
Something with Ph and ORP results doesn't make any sense:
The ph is steady 8.5 day and night
the ORP is very low , at 100 mv.
I have calibrated the probes , twice.
any advice ?
