Home Remedy for Cloudy Pool Water

By Lauren Treadwell

Cloudy pool water is not only an aesthetic problem, it also can cause health issues. Cloudy pool water can sting the eyes of swimmers and hold bacteria and other microorganisms. The causes of this problem include low chlorine levels, unbalanced pH, hard water, algae, bacteria and alkalinity.

Clean pool

Having a clean pool is the first step to keeping the water clear. Empty the pool's water and use a fiber brush to clean the pool, suggests DoItYourself.com. When the water is refilled, test chemical levels. If needed, add chlorine to shock any remaining unwanted growth.

Baking Soda

Add baking soda

Arm & Hammer says baking soda is a naturally occurring substance found in organic beings. Baking soda has the ability to regulate pH; this natural ability is what makes baking soda perfect for clearing pool water. Follow the measuring instructions on a 12-pound bag and add the correct amount to your pool to restore pH balance and clarity.

Use copper solution

Ecosmartepool suggests a method for clearing and preventing the reoccurrence of cloudy pool water at home. It involves sending water through a pump that ionizes it. Test the water's chemical levels weekly. Add copper to the pool after testing chemical levels. The copper reacts with water to make it inhospitable to algae and bacteria growth.

Aluminum Sulfate

Pool skimmer

Many cloudy-water-causing particles are too small to be removed by a pool filter skimmer's net. These particles stay in the water and make it dense. DoItYourself.com suggests using aluminum sulfate. Add 8 ounces of the chemical to your pool per 10,000 gallons of water to collect the illusive particles. The aluminum sulfate, when mixed with water, will react in a manner that causes the small particles to stick to one another and clump up. Once the clumps have settled to the bottom of the pool they can be vacuumed with a pool vac or filtered out. The site recommends repeating the process until clarity is restored to the pool water.

Pantyhose and Socks

Socks

Pantyhose are made from a fine fabric that can trap small particles. Place a pair of pantyhose over the return pump to catch any particles the regular pool filter may have missed. You also can put a pair over the basket of your pool skimmer and trap particles as you clean your pool.

Another wardrobe mainstay can be used for clearing cloudy pool water. If, once a week, you have swimmers get into the pool wearing a pair of socks on their feet and hands they can scoot across the bottom of the pool and rub the walls from top to bottom to clean off any algae that may be growing. Rubbing off the algae once a week will prevent murky water.
