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.
