2nd year with Intex 10x30 pool.

Okay- just filled for 1st time. Following the directions. Making it up to two cups. But as soon as I ran the numbers with the test kit the next morning- the choline level was great the pH was high. How do I fix that?

1. Get a gallon of distilled water at Walmart.
2. Mix 1/2 cup of pool water with 1/2 cup of distilled water. (Must be *distilled*!) Re-test pH

There are 2 possibilities: (a) your pH is actually high OR (b) your previous pH test was invalid, because the chlorine was over 5.0

The pH test in cheapo OTO/phenol red kits is only dependable up to chlorine levels of 5.0. Above that, and you may get a false high reading. Distilled water doesn't change pH much, but will dilute the chlorine.

If it's actually high, you'll need to get a bottle of granular pH down and use that. The SS Recipe may need modifications for pools as small as yours; I really never planned if for such low volume pools. When the pool is that small, dosing becomes more difficult and the effects of a single swimmer on chemical levels can be large.
