The pH liquid drops are my bane of my existance at the moment. We have well water with a pH of around 8.2. I've got a RO
kit (ph around 6.6) and use a blend of 75% RO
to 25% well. I would love to know what pH is now. Naturally, my API ph drops are a bright blue with no hint of green which suggests 7.6 (or higher). And my API high drops are kind of weak tea that doesn't really match anything on my scale. Sometimes I think it's around the 7.4 color. Sometimes I think it's around the 8.0 color. I doubt it's the latter with my mix.
I looked at other kits and they pretty much use the same dyes and cover the same ranges. Elos was a possibility. And I looked at the cheap pH meters and the >$100 ones. I read up on the calibrations and the storage and how they break or mismeasure and....
...and I eventually said (BLEEP) it. I'm reliably sure that my pH is somewhere around mid-7 and that's good enough. Instead, I'm watching my KH
values. Untreated, it was around 14. And with my 75-25 blend, I'm always at 6. I would love to know where my pH ended up. But ultimately, it's not that important for me to pin down. I'm more interested in generating water that's as consistent as I can get it from week to week.
