New Pebble - first tests

[dawndenise]

First - my bad. The 1# package of 62.4% CalHypo never claimed to shock a 16,500 gallon pool, it was 1 package per 8000 gallons. I got the 16,500 number from my OTHER brand of CalHypo, the 73% brand.

Now for good news. I added about 2# CYA yesterday, half about 1PM, 1/2 about 7PM. The pool actually held some Cl through the sunny day, but still only measured 1 total and less than .5 free at 8PM. At 8PM, added 1# of 73%CalHypo.

Total Cl added yesterday was 1# 62.4% CalHypo in the AM, 546 oz 6% bleach at 1PM, when my test showed 0 Cl, and 1# of 73% CalHypo.


This morning's readings show:
Cl 5+ (10+ on the 2x test, maybe 9 on the 3x test)
Free Cl 5+
pH 7.5
TA 80
CH 110

I think we're getting there. Will add appropriate amt of baking soda to raise TA today, as I didn't do that yesterday - already adding a lot of other stuff. This AM, I've already added my last 1# bag of the 62.4% CalHypo which should get me to the 15-16ppm mark.

I've also ordered stabilizer tests - don't plan on adding any more stabilizer until I can test.

I'm anxious to see if that amount of CYA I added yesterday might help hold chlorine today.

Question on the CH drop test: When I did the test yesterday, the initial color was a light pink, rather than red. Today, it barely looked like a pale pink. Adding drops changed the color, but to a very light green rather than a blue. Results still valid?

Thanks for all the help.

The stabilizer you added yesterday probably won't fully dissolve and show up for at least 4-6 days....you need to wait at least that long to test for it again, or adding more.

By the time my tests arrive should be about perfect timing to test this dose of CYA. Thanks for the input.

I'm confused. I'm having a hard time distinguishing mid-vial color changes when I do the 2x and 3x Cl testing. All I know for sure is that my Cl is 5+ and my free Cl is 5+. How long should I keep shocking my pool? Water color is clear, but I can stir up small gray clouds off the wall and floor when I brush. Today is windy and we have all of Lubbock and Amarillo blowing through and landing in my pool so I had some brown dirt clouds while brushing. My PB has yet to install my Polaris.

Yesterday 1PM, Cl 5+, free Cl 5+
Yesterday 7PM, Cl 2 , free 2
Added 1# 73% CalHypo (supposedly a shock level for 16,500 gallons)

This AM: Cl 5+
Free Cl 5+
pH 7.5 or slightly higher
TA 80
CH 110

I haven't added any baking soda in the past few days as I thought I might because right now my pH seems to be relatively stable.

Should I just give the 2x and 3x test results my best guess and treat accordingly to maintain a shock level? I really have no way of knowing if I've attained a shock level for more than a few minutes since we've had the pool.

Thanks for any advice.

Didnt know it was a good idea to shock a brand new pool heh oh well.
