How do you test PH?

[Foxchase]

How do you guys test PH most accurately?

I have an old API from back in my FW days, the Red Sea one and the Hanna PHeP+.

The API pretty much always says 8.2.
Red sea gave me a result of around 8.
Hanna says 8.53

Are any of these reliable? Is there something better out there?

From my Expirience API ph test is not very accurate.
I found ph probes to be more accurate then test kits.
I use apex ph probe and that works good. I also have
a seneye that also test ph and that seams to be more accurate. I believe PH is very important if I didn’t have a controller I would use the Hanna

I use the Salifert test kit.

My Apex tests PH. So it's always available. But it is not a number I pay attention to.

Same here, I have never checked mine! Ones I used a very cheap stick but didn’t even pay attention

I use an Apex for tank pH and my calc reactor pH. I don't really pay attention to my tank pH though. It pretty much stays stable at 8.15/2ish.
