5 Things to Know About Using Household Bleach in a Pool

Household bleach and pool chlorine are the same chemical Both are sodium hypochlorite. Pool chlorine is just stronger, typically 10–12%, while household bleach is usually 6% or 8.25%.

You need 1.5 to 2 times more bleach than pool chlorine Because bleach is weaker, adjust the volume. If a pool calculator says 1 gallon of 10% chlorine, use about 1.6 gallons of 6% bleach.

Only use plain, unscented bleach Avoid scented, splash-less, or concentrated bleach with additives. Those cause foaming and disrupt pool chemistry.

Do the math to get the right dose Calculate: (desired chlorine % ÷ actual bleach %) × required volume. Check the label for exact strength.

Bleach works in a pinch but pool chlorine is better Bleach is a fine backup, but actual pool chlorine is cheaper and easier per unit of chlorine.
