Pool sanitization remains crucial despite the return of chlorine availability. Chlorine eliminates viruses and bacteria, preventing swimming-related illnesses such as diarrhea, skin infections, and ear infections. Determine chlorine needs based on pool size and usage, with estimates ranging from 25 to 50 pounds for a 20,000-gallon pool. Consider Doheny’s stabilized 3-inch tablets, individually wrapped for easy storage and longer lifespan. Invest in all-in-one tablets for enhanced water treatment, including stain prevention, algae control, and scale inhibition.
