How do you stop chlorine from evaporating?

In the simplest of terms, a pool conditioner or stabilizer helps your chlorine stay in the water longer. In other words, it prevents drastic chlorine loss. More specifically, it binds to chlorite ions (your free chlorine), making them impervious to the sun's rays.

Is shock the same as chlorine?

Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock.
