I have not kept up with my spa like I should. I mean, I shock it regularly and the bromine level is okay, but when I checked the ph tonight, the water never did turn red, it was yellow like the bromine color. I redid the test, adding 5 drops of the 0014 to the test kit and it was very yellow. Is this indicative of low ph? should I increase it? Water looks great!
