Has anyone tried the PH or ORP probes from AliEpress?
I am seeing most of the PH probes are in the $5 - $10 range, and the ORP probes are in the $15 range. Much cheaper than the normal probes we have been buying.
I am ordering the conductivity probe to monitor salinity (requires rewiring) and might try one of the orp probes as well.
