The Science of CO₂ Pool Dosing
How a simple gas can replace expensive chemicals, save you money, and make pool care easier
What is CO₂ Dosing?
CO₂ dosing is a modern approach to pool maintenance that uses carbon dioxide to naturally lower and maintain your pool's pH level.
When CO₂ dissolves in water, it forms carbonic acid (H₂CO₃) - the same mild acid found in sparkling water. This gentle acid effectively lowers pH without the harsh chemicals traditionally used in pools.
Unlike muriatic acid, CO₂ is:
- Safe to handle and store
- Impossible to overdose
- Environmentally friendly
- Delivered right to your door
How CO₂ Lowers pH
CO₂ gradually and safely lowers pH to the ideal range (7.2-7.4)
Why CO₂ Works Better
Self-Regulating
CO₂ naturally reaches equilibrium in water, making it impossible to over-acidify your pool. It stops working when it reaches the target pH.
Maximizes Chlorine Efficiency
By maintaining the ideal pH of 7.2-7.4, CO₂ ensures your chlorine works at peak efficiency - up to 80% more effective than at higher pH levels.
Safer for Equipment
Unlike acid, CO₂ won't damage pool surfaces, equipment, or plumbing. It's gentle on your pool but tough on pH problems.
The Pool Store Secret: Your Chlorine Is Wasting Money—Here's Why
Chlorine Effectiveness by pH Level
Why Your Pool pH Keeps Rising (And How We Fix It)
Pool pH naturally rises throughout the week, reducing chlorine effectiveness. See how our CO₂ system maintains optimal pH levels automatically.
Traditional Pool
Problem: Pool pH naturally rises over time due to outgassing, salt systems, and other factors. By the weekend, your chlorine is barely working.
- pH constantly rises, requiring manual acid addition
- Chlorine effectiveness drops to as low as 20%
- Requires weekly testing and chemical adjustments
- Inconsistent water quality throughout the week
With CO₂ Control
Solution: Our CO₂ system automatically makes small, precise adjustments to keep your pH in the optimal range 24/7, maximizing chlorine effectiveness.
- Automatic micro-adjustments maintain perfect pH
- Chlorine stays at 80% effectiveness all week
- No manual testing or chemical additions needed
- Consistent, crystal-clear water every day
With CO₂ control, your chlorine stays 80% effective all week long, saving you money and keeping your pool cleaner.
Most pool owners save up to 50% on chlorine and other chemicals while enjoying better water quality.
