MY POOL BACK UP = CLOROX!
Open the pool early, can't find liquid chlorine, USE CLOROX!
If you get an algea problem with your pool, and just can't get the water clear after treating your pool, USE CLOROX!
Bugs hanging around the pool, USE CLOROX at night, the bugs leave.
When you close your pool, and the chemicals bubble up, ADD SOME CLOROX!
If you run out of pool Chlorine, go ahead use CLOROX = (I use 4 gallons for a 24' pool).
Clorox is NOT as strong as CHLORINE, but it is SURELY a great back up and helps keep the pool clean.
