Chlorine Lock ????

[poolrescue30]

Ok, I ordered a TF100 kit, my old 5 way kit is worthless. Where can I get those good strips, around here they only have aquacheck ones ?the pool store is overnighting my water sample to the chemical company tomorrow , so hopefully we'll have test results by Wednesday/Thursday.

Update:
the pool is still a little cloudy from all the Calcium Hypo that I put in over the weekend.This morning I put in a gallon of 6% bleach .I just tested it with a FAS-DPD test kit.I did it twice , filled it till the 25ml mark, and it turns a nice pink when i put the powder in, 2 drops (multiplied by .2) turns it clear so that would indicate .40 ppm of FCL and after turning it pink with the R0003 , it only took 1 drop to turn it clear, which would indicate the CC is .2ppm.
Are we winning this long battle ?? Should I pour in 8-10 gallons of 6% bleach to shock it overnight ? or wiat for the chemical company's water test result which should be in in the next couple of days ?? THANKS

YES!!! YOU ARE WINNING!

It's been a long fight..

We did it !! Thanks everyone for your help. I couldn't get to Walmart last night, so I picked up 7 128 oz.jugs of 5.25% bleach in my local store poured it in at 7:30pm last night. Just tested the pool with the FAS-DPD kit. Filled it to the 25mml mark. Turned really dark pink when the poweder went in. Took 35 drops to turn clear, which indicates 7ppm of FCL, it stayed clear after the R003 went in so I think we got rid of all the CC !!!!! Now how do I keep it good ??? Also I think my CYA is at 100, do they make unstabilized chlorine tablets ? Or should I just use Bleach to maintain the level ??THANKS A LOT !!

[CarlD]

Great! Maintain it for 24-48 hours! If your CYA is 100, you'll need to keep your FC very high--check the Best Guess table for the range (I should have it memorized but I don't--I think it's 8-15ppm with shocking at 25).

Next, the only unstabilized tabs are the Cal-Hypo Duration by HTH and similar by Pool-life (?) You CANNOT PUT THEM IN A PERMANANT CHLORINATOR!

I just add a gallon of bleach every other day or so.

The pool is absolutley perfect, crystal clear !! What is interesting is that I had a green "stain" about 12 x 12 inches on the liner in the deepest part of the pool. I know that's where the leaves that were in the pool when it was closed last year. I thought the liner was stained from the leaves themselves , but now after all the LC and Calcium hypo shock. It is gone. I'm assuming it was some kind of mildew or mold on the liner that was eating up all the FCL ? How do I prevent this in the future ??

You maintain your FC levels EVERYDAY and vacuum and brush your pool at least once a week!

(BTW, congratulations on a successful fight!)

[poolrescue30]

Thanks CarlD , couldn't have done it without you, Chem_Geek and the other posters. It was a very long fight, wors one I had in 11 years of pool ownership. I did a CYA test myself, once yesterday and again today CYA is clearly 50 using the tube and black dot test, so I think we're in good shape, thanks again.

I guess that means it's time to put your pool to an unusual use...
