Chlorine Lock ????

[poolrescue30]

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 !!

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.
