first PS234 test

Hi, Sharon,

The Cal-Hypo will not add stabilizer...it does add a little calcium which is fine for your pool.

I put mine directly into the skimmer....pump running. Very dissolvable.

If you put it in in the daytime, it will be quickly consumed by the Sun....very ineffective.

Put it in the skimmer at dusk. Do not be surprised if it is completely gone next AM. In fact, you should test for FC tomorrow AM and be prepared to repeat the Cal Hypo next evening.

5-10ppm is too innaccurate for your dosage. You must get to 10ppm to reach breakpoint (shock) level. My chart say 3.25 lbs of Cal Hypo will get your 25k pool to 10ppm.
