Good afternoon, I am hoping I can get some help with my pool issues and chemistry question. Our pool is a 100,000 L in-ground vinyl lined pool with a Zodiac SWG. I own a K2006 Taylor test kit. 2 weeks ago when we opened the pool it was green so I read up on the Pool School, went out and bought a bunch of chlorine and started my day. My cya level was 0 so I added 2.5 kg stabilizer 3/4 days previous to adding chlorine. I then shocked it up to 25 based on my cya level(or what I thought it was) and it started to turn....yippeee!! I continued to add until I thought it was holding, but it never seemed to stop being cloudy. Should I have kept on adding to the 25 even for days on end?
I finally took a water sample into the pool store and the only thing out was the cya level which they said was 100 although it seemed to be 60 on my test kit. If the cya level was truly 100 then I didn't add enough chlorine correct?
So skip forward to this week, the pool is turning green again although I can see the shallow end now which I could not before. Tomorrow I will go out and buy some more chlorine and restart the process. But before I do I wanted to try and get my ducks in a row so to speak.....
When testing the water I never seem to be able to get a CC number. I followed the directions on the kit and it never seems to turn pink when I add the 5 drops of R-0003. What could I be doing wrong?
My levels were
11.5 FC(I added 20 L yesterday morning)
cya- 50(according to my kit)
I haven't added any salt yet as I don't want to waste my money, beings I had to drain some of the pool to try and get the stabilizer level down.
And one last comment that is perplexing me......When I test at home my FC level was still 10 when I took the sample into the store, they said it was 4....does anyone know why the discrepancy, I knew it would be higher as I was following the program.....
Any help would be much appreciated, sorry to ramble on so long but I wanted to include as much info as possible. I am going to order some more stabilzer refills and am hoping that will solve maybe part of my problem.
Thanks so much for listening!!
