5pm 6/14 CST: Just tested pool water with following results:
FC-2.0
CC-5.0
ph 7.2
TA-140
CH-200
CYA-39
Went to Pool Calculator and entered all above info. It told me to add 3.5 121 oz jugs of 8.25% bleach, which I just did. Will check tomorrow am for new test results.
Good job using the PoolCalculator. Larry, you should check in an hour and add enough bleach/liquid chlorine to get back up to 15FC, shock level. Do this as often as you can, especially while the sun is off the pool. All the chlorine goes to fight nasties and none is lost to the sun. The part of the Shock Process that folks don't usually get is the NEED to continually raise FC back up to shock level as OFTEN as possible. If you are home and can do it every hour, that is great!
Am trying to bring CC # down to acceptable.
Following the shock process in pool school will take care of the CC. Question: If CYA is a stablizer and tends to increase longevity of chlorine, should I add some stablizer.
No, you are fine at about 40ish for now.
This makes around 18 121 oz. jugs of bleach this week. Sorry to keep asking, but I'm a little confused; when I get the FC to 15, will I need to keep adding these large amounts of bleach.
We cannot tell you how many jugs o'bleach it will take, but you got plenty of CC that has to burn off before the FC starts holding. You just have to keep hammering it
I still have some tri-chlor granules from last year that I can add to raise CYA, but am reluctant because I think all my problems last year were due to high CYA levels. That is why I drained 75% of pool water (at risk, accd'g to pool store, of ruining my liner).
Do not add any granular chlorine.
Liner and water are fine and clear at this point, but am apprehensive about tomorrow's water test results.
Stop worrying. We'll get this sorted out for you. This problem did not happen overnight, and it will not go away overnight. We will help you take control of your pool. Once you complete the shock process as described in Pool School, you should understand enough that you will not have to shock your pool again. I had QA Chemistry 45 years ago in college and never thought I'd use it again!
Yeah, let's be thankful it is just a pool and not rocket science
