How to maintain a swimming pool (a complete guide to perfectly clean water)
Before you can fully enjoy your pool or properly care for it, it's worth brushing up on all its parts. Knowing the basic components of a pool and their functions helps keep everything running smoothly – and makes it easier to troubleshoot problems when they arise.
Pool maintenance is not complicated if you understand the basic rules. In this guide, we will show you how to maintain your pool properly , with specific values and professional advice from practice.

🔵 1. Basics of pool maintenance
Every pool is maintained through three key elements:
water circulation
pool cleaning
chemical equilibrium of water
If one of these three systems is not working properly → the water becomes cloudy, green or unsuitable for swimming.
🔵 2. Ideal pool water values
This is the most important part that most pool owners overlook.
Parameter | Ideal value |
pH | 7.2 – 7.6 |
Free chlorine | 1 – 3 ppm |
ORP | 650 – 750 mV |
Alkalinity | 80 – 120 ppm |
Salinity (electrolysis) | 3 – 5 g/L |
👉 If the pH is not in range, chlorine does not work properly — no matter how much you add.
🔵 3. Water circulation (pump and filtration operation)
Without good filtration, there is no clean water.
How long should the pump run?
minimum: 8 hours per day
optimal: 10 – 12 hours
professional: adaptation to temperature and load
👉 Rule:
Water temperature (°C) ÷ 2 = minimum pump operating hours
Filter maintenance
sand filter → backwash every 7–10 days
cartridge filter → rinse every few days
DE filter → high precision, regular maintenance
💡 PRO TIP: Adding a small amount of DE powder to a sand filter increases filtration and removes cloudiness.
🔵 4. Regular pool cleaning
Without cleaning, there is no stable water.
Weekly routine:
remove impurities (skimmer or net)
brush the walls and bottom
vacuum the pool
What actually goes into the water:
dust and sand
sunscreens
sweat and bacteria
organic waste
👉 That's why filtration alone is NOT enough.
🔵 5. Chemical pool maintenance
Most common mistake:❌ adding chemicals without testing
What you need to follow:
pH
chlorine (or electrolysis)
alkalinity
How to add chemistry correctly
test the water first
correct pH
add disinfection
Run the pump for at least 6–8 hours
🔵 6. Shock treatment (when and how)
Shocking the pool is essential in situations such as:
after the rain
after a large number of swimmers
in cloudy or green water
Rules:
it is done in the evening
the pump must run for at least 8 hours
do not bathe until the level drops
🔵 7. Most common problems and solutions (SEO key)
🔧 Cloudy water in the pool
Cause:
poor filtration
high pH
small particles
Decision:
check the pH
do a backwash
add flocculant
🟢 Green water (algae)
Cause:
chlorine deficiency
poor circulation
Decision:
shock chlorine
algicide
swimming pool cleaning
⚠️ Chlorine does not work
Cause:
pH too high
👉 This is the most common problem in practice.
🔵 8. Electrolysis - the most advanced way of maintenance
Imagine a system that continuously measures, analyzes, and optimizes your water chemistry - that's electrolysis. The most advanced maintenance method that eliminates guesswork and manual chemical additions.
👉 Advantages:
stable water
less chemistry
less work
🔵 9. How to maintain a pool throughout the season
Spring:
cleaning
water balancing
Summer:
regular maintenance
chlorine and pH control
Autumn:
preparation for closing
🔵 10. Most common mistakes in pool maintenance
adding chemicals without testing
infrequent filter cleaning
poor circulation
ignoring pH value
👉 90% of problems come from this.
🔵 11. Professional advice from practice
always adjust the pH first
Filtration is more important than chemistry
cloudy water is a filtration problem, not chlorine
stable water = less costs
🟢 Conclusion
Pool maintenance comes down to simple rules:
✔ good filtration✔ regular cleaning✔ proper chemistry
If you stick to it, the water will be clean, safe and stable throughout the season .
