Hey guys,
Having some trouble with my PM2/Salinity readings. Did a bunch of research on the forums. Haven't seen this issue anywhere. Basically when my skimmer is on my Salinity drops 2 points?
I'm familiar with the calibration process, temp compensation, margin of error, etc. The probe is less than a year old and just recently calibrated.
This all started about 3 weeks ago. Corals were looking a little pale and nutrients seemed very low so I decided to lower my skimmer run time to 12hrs vs. 24/7 to try to dirty up the tank a little.
Things I've tried:
Calibration
Inspected the skimmer (I was worried about micro bubbles_ None found)
Interference from other probes/power lines so I moved the conductivity probe wiring away from all other wires
Moved the probe location (12-16 inches away from original spot, still in the same section as skimmer. Might need to move it further away? But why it used to work fine there?)
Any Guesses?
Maybe my skimmer pump is leaking some current in my tank? (Reef Octopus Elite 220 INT with a Varios 6-S DC pump) Gosh!!! I hope its not my skimmer pump...its only 1 year old?
Many thanks for all opinions.
