ORP is usually monitored when dosing ozone, but can be utilized to track trends, either up or down. Say for instance, something dies in your tank and you're unaware of it, you would see a drop or spike (most likely a drop). The only time I notice a swing, is after a water change, but nothing to be alarmed about. I think a salinity probe is more important, it's not super accurate, but you would notice a change, which would prompt you to check. Honestly, the most important probe is the temp probe, pH is second, salinity third and ORP last. Just my two pennies.getting ready to settle in for the night and watch a couple hundred videos on how to tweak this bad boy just right. One quick question i probably wont find on there is i have apex lite system with no orp probe. I have added FMM - leak detector, VDM for stream cables for tunzes. How important is the orp probe??
Btw, you should check out Derrick's live stream (reef automation) tmw morning (depending on where you live). Good info and he always gives away stuff, so win, win.
