Howdy all. I have been lurking here for a while in preparation for buying a house with a pool and it has finally happened. I received my taylor test kit the other day and started my adventure with pool chemistry. I ran into a couple roadblocks that I was hoping to get some clarification on if I could. The pool is a fiberglass diving pool of approximately 18k gallons. The previous owner used that fast dissolving chlorine in a tub that you just throw into the pool. The following are my test results:
FC - 10.4
CC - 0 ? Im not 100% on this, but according to the sticky thread here it appears that I did things right. I added the reagent and the water stayed clear, suggesting 0 CC
Ph - 7.4
TA - 110
CH - ?? This one I am very confused on. I ran the test using the smaller sample size and after 14 drops (350) the water turned a light sky blue. I wasn't sure if that was the right color so I kept adding. At 28 drops (700) there was no visible change to water color and I stopped. Is the blue supposed to be vibrant, or just a light sky blue color?
CYA - Registered off the scale. The dot disappeared with only approx. 1/4" of water in it, suggesting an astronomical score on this test.
Based on these numbers, I am thinking that I need to drain the pool and basically start fresh. Because it is a fiberglass pool, I am planning on draining it by approx. 1/4 of its total volume at a time and repeating the process 3-4 times over the period of a week or so. I can also use this time to pull the D.E. filter out and give it a good degreasing/cleaning using the methods I have seen on the forums.
I wanted to check with you guys and see if these steps seem appropriate and if so, if anyone has any recommendations or tips/tricks for me.
Thanks for any info you can provide!
