I posted a few days ago about not being able to get a reading on my pH.
I had let my waterfall run for a very long time and thought that the pH had gotten high (it typically tracks upward anyway).
I discovered that my SWG was running for too long and had driven my FC up to 16.
When FC is that high, you can't get an accurate pH reading.
I have waited for my FC to drift down (turned off the SWG) - it is now 4.5.
I still cannot get a reading on pH - it is a very deep orange color that doesn't match anything on the color block.
When I put only 1 drop of pH reagent in, it looks like it measures 7.2 (very light orange-ish color), but by the third drop it turns into this very deep orange-reddish color
that doesn't match anything. I honestly have no idea if my pH is really high, or really low.
I have put quite a bit of muriatic acid in the pool over the last couple of days, guessing that my pH is high, but it does not seem to be changing the color when I test.
Perhaps it is extremely low?
This is really getting frustrating - I can't seem to recover the pH into a range that I can read.
