    Default Losing 3 ppm of chlorine a day

    Opened pool 12 days ago. It was green as a pond. Held it at shock level till pool was clear. At about 6 days in it was blue but cloudy so I treated it with 20 oz of Polyquat. It cleared up in about 2 days. Since then I let it lower to around 6 pmm. I have had to add 1 gallon of bleach a day to maintain it. I also added salt as I was thinking about getting a SWCG and read on a thread that you could have salt water even if you do not use a generator for the feel of softer water. I added about 150 pounds.

    PH 7.2
    Alk 75
    CYA 55
    100 cal

    I know my PH and Alk is low. How should I fix that and when? Do I wait till I get my chlorine fixed?


    Thanks for any help

    First, maintain shock level (from the Best Guess chart) until 1)water is clear (sounds like you're already there) 2) cc is 0.5 or less, and 3) you don't lose more than 1 ppm of FC overnight.

    Ph is low but still within range, so focus on chlorine right now. Alk is nothing you need to worry about yet.

    Question: was cya higher than 55 when you closed your pool?

    I don't remember. I know it was very low when I opened it. We have a mesh cover and a sump pump and had a good amount of precipitation so the water was diluted quite a bit. I used dichloride, as I always do, to open it and get my CYA back up. I did use a little too much as I usually keep it at around 40. Can't test my cc because I ran out and am waiting for it to come, but when I tested it 4 days ago, I had no cc, which is why I'm a little confused. The other thing that confuses me is that it was 7 after I add a gallon last night, 3 when I test it around 11am, and then stayed there all day- 85 and sunny. I would have expected it to drop some. I normally would have added bleach by now but I wanted to see what everyone had to say.

    I also ran the filter with some DE. Should I continue?

    Bacteria may have eaten your cya from last year causing ammonia in the water. That doesn't change what you need to do. Shock as I mentioned before. If you can't test for FC and cc right now, get a cheap oto test kit and keep it off the chart dark yellow.

    I can test for FC. I just got all new regents and got/ordered R-0002 instead of R-0003 (oops) so that's all I'm waiting on. It's a shame I can't buy it at a pool store. I'm at 3 and just added 6 gallons and I will test again in a couple hours to make sure I'm above 20 before I go to bed.

    Thx!
