PH test extremely pink?

Put a white piece of paper or white paper plate behind the block. This should give a better sense of color.

With FC above 10, the pH test isn't valid.

Looks like a 7.5 with 4 drops in it. FC is at 10. View attachment 485711

Chlorine is on the left, 1-5. Bromine is the right scale, 1-10. I've used many of those kits just to quick sample, and FC always reads way higher than my trusty Taylor kit and DPD powder test. I can assure you that's actually at best 2.0 FC on a DPD test. The pH side I've never paid attention to. Only trust my kit for that - seems on the higher end of the 7's, it want's to run darker than actual pH.

And you're flirting with FC being too high to trust the pH test, might be skewing the colors.

That's very true too.

It was way off before I even added any chlorine yesterday when I first opened. This is year 3 with this pool, and the test looked way off so I made this post. I know that high FC makes the test invalid.

There is no water or test reagent in the chlorine side in any of the pictures on this thread. I am concerned with the PH side of things.

The Taylor K1000 I was using previously seemed like a much higher quality block. Ill buy one and swap it out
