4 Reasons Pool Chlorine Is Better Than Household Bleach

Pool chlorine is stronger and more concentrated Household bleach is typically 5–8% sodium hypochlorite, while pool chlorine is 10–12%. You need less pool chlorine to achieve the same sanitizing effect.

Pool chlorine includes a UV stabilizer Most pool chlorine contains cyanuric acid, which protects chlorine from breaking down in sunlight. Household bleach lacks this stabilizer, so you’ll have to add it constantly to maintain levels.

Pool chlorine has clear dosing instructions The label on pool chlorine tells you exactly how much to add for your pool size. With bleach, you need a pool calculator or test kit to avoid guesswork that leads to algae or eye irritation.

Pool chlorine costs the same or less for the job For the same price, you get a stronger, stabilized product that’s designed for pools. Save the bleach for laundry unless this is a last-minute emergency or a tiny kiddie pool.
