How Often Should I Test My Pool?

[Dr. Spike]

I test only FC, CC, and Ph daily. I test the Alk weekly. I don't test the Cal too often as I have a vinyl pool, but if I had a gunite pool I would test it weekly. The stabilizer I don't test that often either, my pool is indoors, I don't have any (well, very little since I opened the pool with pucks after being 'pool stored'). Oh yeah, I check the temp daily, because I like to know how cold I will be when I swim.

As for Cl levels, check Ben's Best Guess chart.

Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . . . 8 ppm . . . . . 15 ppm . . .. 25 ppm

EDIT: Hmm, beat me to the post.
