Looking For Some Advice

[Watermom]

I'm not clear on something. Have you added a total of 10 or 16 lbs. of CYA? Also, how did you add it and how many days has it been since you last added it? (If you added it to the skimmer, did you backwash any within 4 or 5 days of adding it?) In regards to the CYA test, you read it when the dot completely disappears.

You need to be running your pump more. Probably a minimum of 8-10 hours a day split into two 4 or 5 hour sessions, although right now while it is still somewhat cloudy/hazy, you should run it 24/7 to allow your filter to do its job clearing the water.

I would say for this big of a pool, only adding 1.42 gallons per night isn't much. That equates to only about 2ppm of chlorine. When you test it in the evenings before you add bleach, what is the cl reading? I would like you to do something. Test this evening before you add bleach and note the cl level. An hour after adding the bleach, test again. Then, test it again in the morning within 2 hours of sunrise and note that level. Then, report all three of those readings here.

TA, pH, and CH all look fine.

You're doing great! Keep up the good work!

(BTW - I agree with your wife --- water in the mid-70s is too cold. !)

I added 6 lbs of Stabilizer through a sock in the return before 6-16-11 within the next few days I added another 3 lbs same method (9 LBS Total) - It has been a couple of weeks so my CYA should show up but it is not what I would except it to be based on your advice and the company that built the pool. When I do test the CYA it is hazy all the way to the top, but it is reading better then when I had 0 CYA. Note: Back Washing I seldom need to do, I will do it just because some times but after I cleaned up all the crap and leaves out, the sand filter stays around 1 - I added the CYA after I cleaned up most all the leaves etc when I could see the bottom though the pool was still very hazy - So I would say that I did not back wash the CYA out of the pool based on how I added it through the retrun and seldom have to backwash.

On to the readings

Last Night

9:30PM - 6.4FC (added 1.42 Gallons Bleach @ 8:30PM)
6:00AM - 5.4FC

In a 40K gallon pool, 9 lbs. of stabilizer will only give you a reading of about 28ppm which isn't really gonna show up in a test. The minimum that can show is usually around 30. I think you just need to add more CYA. Add about 4 more lbs and then retest it in about a week and report your level. That should give you a level that can be detected and it should read about 40-45ppm of CYA.
