Dichlor to Liquid Chlorine Conversion

Find out exactly how much liquid chlorine bleach equals a dose of Dichlor shock powder to maintain the exact same sanitization power.

Quick Conclusion
10 ounces of granular Dichlor shock (56%) provides the same Free Chlorine boost as 108 fluid ounces (almost a full gallon) of standard 10% Liquid Chlorine.

Pool stores love selling buckets of Dichlor shock because it's highly profitable and stable. However, educating yourself on how to replace it with liquid bleach saves your pool from the dreaded CYA crash.

Actionable Steps

1. Look at your typical routine (e.g., 'I add 1 lb of Dichlor every week'). 2. Convert 1 lb to 16 oz. 3. Input 16 into the calculator to see the fluid ounce equivalent of liquid chlorine. 4. Buy liquid in bulk hardware jugs.

Pro-Tip

If you are using household Clorox bleach instead of professional 10% pool chlorine, make absolutely sure it is 'Splashless' or 'Scented'. Standard plain bleach is usually 6-8%, which means you need to add 30% more than the calculator suggests.

Frequently Asked Questions

Why convert from Dichlor to Liquid?

Dichlor adds massive amounts of Cyanuric Acid (CYA) to the water. In the middle of summer, using Dichlor exclusively will rapidly push your CYA over 100ppm, causing chlorine lock. Switching to liquid stops CYA buildup.

Is liquid chlorine as strong?

Liquid pool shock is usually 10% or 12.5% Sodium Hypochlorite, whereas Dichlor powder is heavily concentrated (56%). You need a lot more volume of liquid to achieve the same ppm.
