Help Deciphering My Taylor Test Results

[Watermom]

I skimmed back through this thread and Al did say early in the thread to use cal-hypo. But, I don't think he was suggesting that cal-hypo SHOULD be used but rather that your CH reading was low enough that you COULD use it. I'd stick with bleach. No chance of the bleach clouding the water up like cal-hypo might.

Switched back to bleach on Sunday! I'm just blindly adding it right now, until I get more reagent (it's on its way).

But I did finally swim in it last night for the first time.

Finally got my reagents today. I was nervous about what might be going on in there, while I couldn't spy.

My chlorine is really high (42.5)!!! I haven't added any bleach since Monday - 1.5 gals. The rest of my numbers look OK

pH - 7.2
CYA - 35
CC - 0

So I finally got rid of the CC - but what can I do about the high chlorine, other than leave it and hope for a sunny day? I haven't been using pucks, either.

I bet you got rid of your CC if your cl really is 42.5!!!! You might want to double check that test again. There really isn't anything you can do to lower cl. Lots of sunny days will drop it.

I hope my reagent isn't bad - I just got it today (the CL reagent was what I had to order). I'll use the other container of 0871 that I got (I ordered 2). I'll repost as soon as I retest.

Yeah, I'm thinking a FC level of 42.5 will kill just about anything!!! But CC is down to 0 P

Well, I just tested the water again (5 hrs since last test). I used the second bottle of 0871 I just received today.

NOW my FC is 41 and CC is 1 - - how is that even possible?

What to do now...

I ordered the reagents from The Pool Source - but it IS Taylor brand.

Should I presume at this point that the reagent is bad? Is it possible to go from just under 20 ppm FC to 41+ w/ 2 gals of 5.25% bleach? And if so, is it possible it held for over 48 hours?

I'm no mathemagician - but that just doesn't add-up to me!

2 gallons of 5.25% bleach in a pool your size (12,500 - 13.000 gallons) would raise your cl by approximately 8ppm.
