Hi all,
I'm new to this forum but I've been a pool owner for 25 years and have done it all... changed and installed filters and pumps, heaters, liners, etc. so I'm not a novice but we all get that annoying problem now and then that we can't figure out. Like this one:
I have a 13,500 gal in-ground chlorine pool and have had no chemistry problems for a couple of years. Last week my floater ran out of chlorine for about two days. Then I realized it when the water became a little cloudy. I shocked it and the next day no chlorine reading.... I shocked it again the next day and again, no chlorine reading. I had to leave for two days so I put plenty of chlorine in the floater and opened up the holes to 15,000 gal level so I'd have chlorine going in.
I came back yesterday and took a sample to the local pool store and the only thing wrong was my alkalinity was 40. They said to put alka up in it which I did yesterday afternoon. They also said to shock it at dusk and I used on pound of supershock. This morning I went out and again NO CHLORINE READING AT ALL....ABSOLUTE ZERO AGAIN ON FREE AND TOTAL CHLORINE. So, something is eating up the chlorine as fast as I can put it in and I can't figure this one out. The pool store said the water was fine except for the alkalinity which is now ok.
My other readings are as follows:
Chlorine 0
Ph 7.2
Alkalinity 80
Hardness 20
CYA 30-50
The water is so cloudy I can only see down to the third step or so and gets worse by the day.
Any advice would be deeply appreciated......thank you!
