So here's the follow up... I drained about 1/3 of the pool and re-filled it, which brought my CYA down to around 60. Then I did another chlorine test, this time diluting the pool water with 3 parts distilled water and got a FC reading of 48 (!!) and a CC of 0, so I guess I had sufficiently chlorinated the water prior to the refill (and then some). I've spent the past week vacuuming, brushing, skimming, and filtering the pool and I'm happy to report that the water is now crystal clear. My current test readings are: FC = 14 CC = 0 TC = 14 pH = 7.6 TA = 90 CH = 300 CYA = 60 I haven't added any chorine since the refill, and it's dropping about 6 ppm per day (with the help of some afternoon rain showers). My original concern was that the water was still cloudy even after I was pretty sure I had shocked the pool properly. Looks like I just needed to brush and filter for about a week to clear all the dead algae that was clouding the water. Thanks for the help.

Well... I guess I have fantastically high chlorine levels. The OTO test turned the water dark orange. Crazy. The last time I added any chlorine was last week... on the advice of the pool store after they tested the water. When the water didn't clear up, I was sure I'd have zero FC, like the majority of "cloudy pool" posters. Huh. So now I guess I drain 1/3 of the pool water and replace it, maybe a couple of times, to try and bring the CYA to 50 or so. Any other advice? Thanks.

Yes, I've double- and triple-checked that I was using the right reagent. I also did do the 50% dilution test on the CYA (per advice in these forums) and came up with a reading of 50. So I think I'm right around the 100 range for CYA. I'll pick up an OTO test today and see what color I get. Thanks for your help.

Hi all - I've recently become the owner of a 20,000 gallon gunnite pool (my first pool). Just received my K-2006 test kit today. My FC tests are off the charts; in fact, I can't get the test water to clear from pink, even after adding more than 40 drops of R-0871 (using the .5 per drop basis). My CYA is 100, but the pool is quite cloudy and I haven't added any chlorine for several days (I was waiting for my test kit before I started shocking). It's hard to believe my FC is over 20, so I'm wondering why I might be getting this result from the test. Any clues?
