Swimming pools are a lot of fun, but maintaining one, and keeping algae at bay, can be both a chore and costly. One alternative many pool owners use to purchasing pool chemicals, is to use household chemicals such as baking soda and Clorox bleach instead. Since sodium hydrochlorite is the main active ingredient in Clorox bleach, it can be substituted for the calcium hydrochlorite available at the pool store, however it must be used in different amounts as the concentration differs. Over-the-counter baking soda is actually completely identical to the alkalinity increaser sold at pool stores.
Purchase regular, unscented Clorox bleach. Today there are many varieties of bleach on the market offering special scents, oxygen or color protection, but these should definitely not be used in a swimming pool. Look on the package to see what the active ingredients are. The only active ingredient should be sodium hydrochlorite.
Use a pool calculator to determine the amount of water held in your pool. Or simply write down the amount of calcium hydrochlorite from the pool store that you are currently using.
Calculate the amount of Clorox to be poured into your pool. You should already know how many grams of calcium hydrochlorite your pool is meant to use. According to Pool Solutions, one gallon of Clorox is equal to approximately 340 grams, so you can use this as your measure for substitution.
Pour the required amount of Clorox into the skimmer of your swimming pool.
For substituting alkalinity increaser with baking soda, simply substitute one to one, according to Pool Solutions, these are the same chemical.
