Looking for a pH probe for apex.

Lemme know if you have one.

Thanks!

Why not just buy a new one from J&L? Are you gonna trust a used one to last?
And you don't need to use a neptune one if you're not worried about lab grade.
Just get the american marine pinpoint if you want to cheap out. It's only $45 and I've so far had them last a few years with the odd re-calibration.

If you want lab grade, check out the reefcrest one. I haven't looked it over yet to see if it's 2 stage, but it's $65ish if you don't want to spend over $100 on a neptune one.
Just be sure to purchase some 7.0 and 10.0 calibration fluid as they are never going to match your controller out of the box.

Hey thanks for the info.
Thought these were all proprietary.
I just want to add one to use on my calcium reactor.
Don't think I need lab grade... Off to google I go!
