Is there a difference in Pool Shock?
Also question is, what can I use instead of pool shock?
Bleach. Also known as sodium hypochlorite, simple household bleach. (which contains 5.25 percent of sodium hypochlorite, the active ingredient in bleach) can get stains out of grout that the baking soda couldn't. Bonus Tip: Bleach can also be used to shock a pool.
Also to know is, is chlorine the same as shock?
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.
