CYA - ?
New pool in the Boston area. Water went in on Aug 10. Startup company came on the 11th. We started the pump and they put some chemicals in the pool. I think it was mostly baking soda to conteract the acid wash of the pebble sheen. I checked the pH every day and kept it around 7.3. The weather was bright sunshine and high 80's most of the time. Wife and kids were away, so no-one went in the pool. Startup Company came back on Aug 20. They shocked the pool (Di-chlor?) and left 5 chlorine sticks in the skimmers (2 in one, 3 in the other). I checked the chlorine level and it was off the chart. On the CYA test, the black dot was visible even when the tube was completely filled. The solution never got cloudy.
Since then, it's been in the 60's and raining. The kids and I have still been using the pool in the rain for about an hour each night. We also had a few other kids in on the 22nd. The heater has been on and off. The pool temparature has been fluctuating between 75 and 82.
I noticed Tuesday, 8/24, that the chlorine sticks were gone. Using my Taylor test kit (Startup company provided it), I checked the chlorine level. It was over 10. I did the test twice, once full-scale (9mm of pool sample) which was off the chart and again at half-scale (4.5 mm pool sample with 4.5mm of tap water) which was still off the chart. Both times, there was no noticable difference when I added the third reagent to check for combined chlorine. I was getting really wet from the rain, so I didn't do the 1/5th scale test. I figured that since it was so cold with no sun that there was still residual chlorine from the shock and the sticks. This moorning, I tried the chlorine and CYA tests again. The CYA test still showed no cloudiness in the sample. The 1/5th scale chlorine test looked like about a 2, so I figure my free chlorine is 10. Still no change when I added the third reagent, so it looks like my combined chlorine is 0.
Can my test results be right? Is it possible that I haven't used up much chlorine due to the weather?
Today it's sunny and expected to go to low 80s. My son will have several friends over to swim most of the afternoon and we're having guests tonight. I bought 3 gallons of bleach yesterday to have on hand. I was planning to check the chlorine level again before dinner. If necessary, I will add bleach so we can go swimming after dinner. Is there anything else I should do?
The pH has been pretty steady even with the rain. I have kept it at about 7.3 by adding a little over a pint of muriatic acid every two days, so I think my Total Alkalinity is O.K. WHen I checked it on the 20th, it was about 80. I forgot to check it this morning.
If my CYA sample is clear, does that mean I have to much CYA or too little? With all the rain, the pool almost overflowed, so I drained about 3 inches yesterday.
My signature says we have a SWG, but I haven't turned it on yet. Pool company said to wait 30 days after the water goes in.
Thanks for the help.
