How to Chlorinate Your Pool with Bleach
Liquid bleach (Sodium Hypochlorite) is the same active ingredient found in expensive "Liquid Pool Chlorine," just usually in a lower concentration.
- Check Strength: Look for the percentage (usually 6% or 8.25%) on the label.
- Avoid Scents: Never use "easy-pour," "scented," or "splashless" bleach, as they contain additives that cause foaming.
- Pour: Add directly to the pool water in front of a return jet while the pump is running.
Why Use Bleach Instead of Tablets?
Chlorine tablets (Trichlor) contain Cyanuric Acid (CYA). Over-use of tablets leads to CYA buildup, which eventually locks your chlorine and requires draining the pool. Bleach is "unstabilized," meaning it adds zero CYA.
Pro Tip: If your pool is green or very cloudy, a maintenance dose isn't enough. You need to follow a full SLAM procedure using our Green Pool Shock Calculator.
Is it Safe for My Pool Liner?
When added properly (with the pump running and pre-diluted or poured into a return flow), liquid bleach is safe for vinyl liners, plaster, and fiberglass pools. It's the same chemical used by professional pool technicians, just in a lower concentration than "liquid shock".
Frequently Asked Questions
Is bleach the same as liquid pool chlorine?
Yes. Both are Sodium Hypochlorite. Pool chlorine is usually 10% or 12.5% strength, while grocery store bleach is usually 6% or 7.5%. Use only plain, unscented bleach.
Will bleach raise my CYA or Calcium level?
No. Unlike tablets or shock powder, liquid bleach adds only chlorine and a tiny amount of salt. It is the cleanest way to sanitize your pool.
