first results of year, re-filled pool end of last year

[vinouspleasure]

latest test:
pool: 28K gunite
fc - 1.2
cc - .4
ph - 7.2
alk - 70
cal - 240
cya - 10

today I threw in another 4 pounds of borax, 3 pounds of baking soda, 10 pounds of calcium and 4 pounds of cya. I also threw in enough bleach to raise fc to 4, hopefully the increase in cya will help keep it in range though I'll probably have to put more cya in to reach goal, I guess the cya can take about a week to show up in tests, so I plan to wait until next sun before testing for it again.

pool is crystal clear.

You are right that CYA takes up to a week to dissolve and you are also right that you may end up needing to add a little more. In your pool, 4 lbs. should add about 20ppm of CYA.

For the next week or so, you'll probably need to add some bleach morning and evening. Once your CYA is up some, you should be able to test and dose in the evenings only.

moving in the right direction, water is perfectly clear, latest test:

pool: 28K gunite
fc - 3
cc - .5 (probably less, used .5 test)
ph - 7.6
alk - 80
cal - 250
cya - 20

I need to add a little more cya (goal is 30-50), I'm at the bottom of the goal range for calcium (250-400) and alk (80-100), should I adjust those up to get into the middle of the range?

You can adjust those two a little if you want but actually, you're probably fine where you are. For CYA, I think you'll do better at 50 than at 30pm.
