How to Lower Pool Chemical Usage Without Sacrificing Water Quality
Introduction
Many pool owners assume that more chemicals mean cleaner water — but that’s not always true. With the right techniques, it’s entirely possible to reduce your chemical usage and still enjoy a safe, clear pool.
At Deep Blue, we help pool owners save money and reduce environmental impact with efficient, high-quality products and smart maintenance strategies. This guide outlines proven ways to cut chemical use without cutting corners on water quality.
1. Maintain Proper Water Balance
If your pH, alkalinity, or hardness is off, your sanitiser won’t work as well — meaning you’ll need more of it.
Ideal Ranges:
- pH: 7.2–7.6
- Alkalinity: 80–120 ppm
- Calcium Hardness: 200–400 ppm
Use Deep Blue’s pH+, pH–, and balancing products with integrated measuring tools for precise, waste-free application.
2. Use a Pool Cover
Up to 90% of chlorine loss is caused by UV exposure. A cover:
- Reduces chlorine degradation
- Minimises evaporation and heat loss
- Keeps debris out, lowering sanitiser demand
3. Optimise Filtration
Run your pump long enough to filter the entire pool at least once per day. A clean, efficient filter reduces the need for extra chemicals.
- Backwash sand filters regularly
- Rinse cartridge filters weekly
- Soak in Deep Blue Filter Cleaner every 1–2 months
4. Shock Weekly to Maintain Chlorine Efficiency
Organic matter and chloramines reduce chlorine’s effectiveness. Regular shocking resets your water and lowers overall chlorine demand.
- Use Deep Blue Non-Chlorine or Chlorine Shock
- Shock in the evening for best results
5. Use a Stabiliser (Cyanuric Acid)
Stabiliser protects chlorine from UV rays. Ideal range is 30–50 ppm. Use stabilised chlorine or add stabiliser separately.
6. Switch to Multifunctional Tablets
Deep Blue 4-in-1 Tablets include:
- Stabilised chlorine
- Algaecide
- Clarifier
- Scale inhibitor
These reduce the number of products you need — and help prevent over-treatment.
7. Address Algae Early
Algae increases chlorine demand. Use preventative algaecide weekly and brush pool walls regularly to avoid blooms.
8. Minimise Swimmer Contamination
- Encourage showering before entering the pool
- Limit sunscreen and oils
- Use skimmers to remove debris quickly
9. Store Chemicals Correctly
Heat, light, and humidity degrade chemical potency. Seal lids tightly and store in a cool, dry place.
10. Use Deep Blue’s Smart Dosing Tools
All Deep Blue chemical products feature:
- Integrated measuring scoops or caps
- Clear dosage charts by pool size
- QR codes linking to our online calculators

FAQs
Can I stop using chlorine altogether?
Not recommended unless using a UV or ozone system. Consider reducing, not removing, chlorine.
Will stabiliser stop chlorine working?
Not if levels are within 30–50 ppm. Too much can “lock” chlorine, though.
Do multifunctional tablets replace shock?
No. You’ll still need to shock weekly to remove organic build-up.
How much can I save by optimising?
Up to 30–50% of your annual chemical costs can be avoided with smart care.
Can I switch between chlorine types?
Yes, but avoid mixing products directly. Rinse feeders and tools between changes.
