Adding Chlorine Every Day

[aylad]

You'll find that the higher the chlorine level, the more you'll lose in a day. You may have gone from 19 ppm to 8.5, but tomorrow you may go from 8.5 to 5....my point being that you probably won't have to spend the $2.50 a day when you're running normal chlorine levels. For example, my pool is in Northwestern Louisiana, in full sun from about 8 AM til about 7PM during the summer. Today's air temp topped out at 104, and the heat index with 87% humidity was 109. I started with 8 ppm chlorine this morning, and just tested it a few minutes ago at 4 ppm (CYA 80). A little low, so I added the large size jug of bleach, which in my pool is a 4 ppm increase. Not bad, if you consider that it's been two days since I had to add any--the last time I added was Saturday--put one jug in in the morning because I had a pool full of kids coming over for the day, and then added another jug that evening after they all got out. None since then til tonight.

With my CYA at 80-90 (intentionally), I go through about 4 of the large jugs weekly during the summer. During the winter, after the water temp drops below 60 or so, I only use 1 of the larger jugs every week or so, and I keep my pool open all year--it never closes.

I think you might have missed the part where Jan said you are fighting something. Until we KNOW your pool is cleared, we may well see further FC drops. If, instead, your FC drop matches Jan's, then you are probably ready to run the maintenance level of 5-10ppm of chlorine.

I don't know why, but this seems to be a season of heavy chlorine usage. I've been adding about half a gallon of 12.5% LC almost every day and am pushing my CYA level up to try to get it to maintain a proper residual level. 1/2 gal of LC is equal to about 1 gal of bleach and costs about $1.70, so I feel your pain. I've had no CC for weeks, my water's clean and my pH is stable, so I'm thinking it's just the heat and sunlight.

Hey Guys

I was glad to see this thread.... I've been using the BBB method since my new liner I guess it was end of may.

My CYA is aprox 60, PH 7.2 to 7.4, temp 90 and I have to add about 3/4 to 1 gal everyday and sometimes the Clorine level drops to 2.8 or so. Once in a while I miss a day and it drops very low. I didn't think I'd have to add the clorine so often. For the most part the water is crystall clear.

I would suggest that you try testing at night after the sun is off the pool and again the next morning before the sun hits the pool. If you lose more than 1 ppm chlorine during that time, then you'll need to shock the pool to get rid of whatever is causing the chlorine demand. With your chlorine dropping that low, it's probable that you have an algae bloom trying to happen.

Thanks! I tested tonight and still low under 2. I'll shock her up on monday and let you know

I wouldn't wait til Monday to shock. You need to do it in the morning if possible or at least tomorrow sometime.
