Chlorine won't stay in pool

[Watermom]

Hi and welcome to the forum. We really need a complete set of current water testing numbers to be able to offer you advice. Can you please post the following for us to take a look at:

We need at least 2 of the following:
FC (free chlorine)
CC (combined chlorine)
TC (total chlorine)

Also:
pH
alk
calcium hardness
CYA (cyanuric acid)

Is it a vinyl, gunite, concrete, fiberglass pool? Also, please tell us ingredient names of everything you have put in your pool --- not just "shock" but actual ingredients. Then somebody here can take a look at better advise you.

Chances are really good that your chlorine is disappearing because it's fighting something in the water and because your stabilizer is zero, allowing the sun to consume what the stuff in the water doesn't. Go ahead and post the info that Watermom requested, and I'm sure we can get you going in the right direction!
