Chlorine Lock ????

[poolrescue30]

Update: I had to be out of town yesterday till this afternoon.I had a friend pour in two 174 oz jugs of 6% bleach , last night at 6pm .This afternnon when I got back i took a sample to the pool store , it showed FCL 0.1 ppm and TCL 0.6 ppm, I hope that means the CC going down is a sigh the problem is going away , although i'm not keeping any FCL in thr pool ?? They suggested 3 lbs more Calcium Hypo into the skimmers and check 3 hours later and then 8 hours later on the FCL level . Does it make sense ???
Thanks

I have told you before: the Cal-Hypo is not better than the liquid chlorine. It even may make your pool cloudy for a while until it all dissolves in, and it will raise your calcium level, which may be harmless.

But unless the Cal-Hypo is seriously cheaper, there's not any point to using it.

The reason they keep pushing it is that is what pool store clerks do. They see a bag of "Shock" and it's full of cal-hypo so they think that MUST be what you use.

But, as I said before: In your water, chlorine is chlorine. And Liquid Chlorine goes to work FASTER because it doesn't have to dissolve first.

CarlD,I appreciate your help. The pool store I go to is family owned an very expensive on their chemicals, but their computer water test, has been used by me for over 5 years. Sometimes I buy the chemicals there, sometimes I go elsewhere. The owner's son has been doing my test himself, he is trying to figure it out. In fact , when he said to throw in 2 carboys of LC, after having already.purchased 2 three daya prior, he threw in the second carboy for free. He had called his chemical manufacturer and spoken to the chemist there and went through all my numbers with him, they suggested the calcium hypo instead of LC,(which their company also sells to the pool store) they said to throw in the 3 bags tonight and test the FC 3 hours later and then tomorrow morning. I did the FAS-DPD test tonight after the 3 hours. It showed 1 ppm of FC and 1 ppm of CC. The chemist suggested 3 bags per 10k gallons of water over the weekend if the FCL doesn't stay in till the morning. I don't want anymore calcium hypo, my pool will be clousy for a month, how much LC should I put in ?thanks
