What does this pH reading say?

[lukefish]

I’m using the NT Labs test kit

and this is the colour I am getting when I test the pH:

my eyesight isn’t great but I’m pretty sure it doesn’t match any of the colours on this chart...

Can anyone help?

My eyesight is not great on these either, but pretty sure those results are saying to get a probe.

What’s a probe?

sorry

Any clearer?

That's pretty easy to read. It clearly says; "Get a new test kit."

Edit:
It also seems to be indicating that your solution may be out of range for the kit?

Great. Didn’t see that in the fine print. Which one do you use?

I think most people who monitor PH use an aquarium probe. They can be used with a monitor controller or standalone. I have found the cheap PH monitor with probe that i got on amazon(around $20 USD) to be accurate(or at least consistent with the much more expensive probes i have on my other tanks). They do need to be calibrated(calibration fluid maybe included with probe or bought seperately)

I have a pH pen, but I don't like it much better than your test to be honest. I have a pH probe that runs my calcium reactor and I have calibrating solutions that I use to calibrate both but I can't recommend either. I believe my pH is at the low end in my tank but it's stable and i don't concern myself with it all that much.

The tests, the strips, all have similar visual problems, or require routine calibration.

Anyone else have a pH checker that wants to give a plug?
