Orp probe for apex

[sergifed91]

I'm just curious is it worth getting the orp probe for my apex unit?

If you plan ozone, absolutely. If it comes with the Apex you're buying, definitely worth having. Spending extra to get one without using ozone? Nah

Thank you. That answers my question. I am going to use two pH probes on my apex then.
