Pools less than 3 feet deep carry the "kiddie pool" or "baby pool" label. The other defining characteristic of these pools is their lack of filtration systems. Pool Solutions points out that small pools may carry an increased risk of pathogen transmission because the small amounts of water warm quickly and don't typically contain pool sanitation chemicals. To combat infection and disease risk associated with high levels of bacteria in the water, parents need to either empty and clean the pool after each use, or add sterilizing agents to the water.
Empty pools that contain only a few inches of water after each use. The small amount of water in these pools allows for high heat from the sun and promotes algae growth as well as bacterial growth. Pour them out and allow them to air-dry. Wash the bottom and sides with a scrub brush and simple bleach solution weekly. Rinse well before refilling.
Sterilize baby pools that contain too much water to effectively empty and refill each day. Add a dose of small pool sanitizer that correlates with the amount of water in your pool.
Use a skimmer to to remove bugs, grass and other debris once or twice daily.
Leave your pool uncovered because covering your pool can prevent pool chemicals from properly airing out, according to Allied Pools. Covers also trap heat, which speeds algae and bacteria growth. Wait four hours after adding chemicals if you must cover your pool.
Add 1/4 to 1 cup of regular household bleach made from 5.25 percent sodium hypochlorite to your baby pool if you don't have access too pool chemicals. Let the bleach work overnight to kill bacteria and algae. Avoid bleach with additives, colorings or at different concentrations than 5.25 percent, advises Pool Solutions.
