Introduction
How often should you maintain your pool? This is one of the most common questions we receive from pool owners in Margem Sul. The answer isn't simple – it depends on various factors such as pool type, time of year, frequency of use and local conditions.
Regular, well-planned maintenance is the key to always having crystal clear water, avoiding costly problems and extending equipment life. Doing too little leads to water quality problems; doing too much means unnecessary costs.
In this guide, we present a complete maintenance calendar with the ideal frequency for each task, adapted to the specific conditions of Portugal and the Margem Sul region.
Maintenance Calendar Summary
Overview by Frequency
| Frequency | Main Tasks |
|---|---|
| Daily | Check water level, remove floating debris |
| 2-3x/week | Test pH and chlorine, clean skimmer basket |
| Weekly | Vacuum floor, brush walls, check equipment |
| Fortnightly | Test alkalinity, clean waterline |
| Monthly | Test hardness, check filter pressure |
| Quarterly | Deep cleaning, check seals |
| Six-monthly | Equipment maintenance, check structure |
| Annual | Complete inspection, replace consumables |
Daily Tasks
What to Do Every Day
| Task | Time | Importance |
|---|---|---|
| Check water level | 1 min | High |
| Remove leaves/debris | 2-5 min | Medium |
| Observe water appearance | 1 min | High |
| Check pump is running | 1 min | High |
Details
Check water level:
- Should be at mid-skimmer height
- Too low: pump may suck air
- Too high: skimmer doesn't work well
Remove floating debris:
- Use surface net (leaf skimmer)
- Prevents sinking and decomposition
- Reduces load on skimmers
Observe water appearance:
- Crystal clear water = all good
- Slightly cloudy = test and adjust
- Green/very cloudy = immediate action
💡 Dica Profissional
In Margem Sul, especially in areas with pine trees (Aroeira, Verdizela, Charneca), daily removal of pine needles is essential. Leaving them more than 24 hours leads to staining and water acidification.
Tasks 2-3 Times per Week
Testing and Basic Cleaning
| Task | Time | When |
|---|---|---|
| Test pH | 2 min | Morning, before swimming |
| Test chlorine | 2 min | Morning |

| Add chlorine if needed | 5 min | End of day |
| Clean skimmer basket | 2 min | Whenever testing |
| Clean pump pre-filter basket | 3 min | 2x/week |
Reference Values
| Parameter | Ideal | Action if Outside |
|---|---|---|
| pH | 7.2-7.6 | Adjust immediately |
| Free chlorine | 1-3 ppm | Add if < 1 ppm |
| Combined chlorine | < 0.5 ppm | Shock if > 0.5 ppm |
Frequency by Season
| Season | pH/Chlorine Tests | Justification |
|---|---|---|
| Summer (heavy use) | Daily | Higher chlorine consumption |
| Summer (normal use) | 3x/week | High temperature |
| Spring/Autumn | 2x/week | Moderate conditions |
| Winter | 1x/week | Minimal use |
Weekly Tasks
Cleaning and Checks
| Task | Time | Importance |
|---|---|---|
| Vacuum pool floor | 20-45 min | High |
| Brush walls and steps | 15-20 min | High |
| Test alkalinity | 3 min | Medium |
| Check filter pressure | 1 min | High |
| Inspect equipment | 5 min | Medium |

Floor Vacuuming
Recommended frequency:
- With robot: can be daily (automatic)
- Manual: 1-2x/week
- After storms: immediately
Signs you need to vacuum:
- Visible debris on floor
- Slightly cloudy water near bottom
- More than 3 days since last vacuum
Brushing
Priority areas:
- Waterline
- Corners and steps
- Behind ladder
- Low circulation areas
Why brush:
- Removes invisible biofilm
- Prevents algae
- Distributes chemicals evenly
Fortnightly Tasks
Intermediate Maintenance
| Task | Time | Notes |
|---|---|---|
| Clean waterline | 15-30 min | Specific product |
| Test calcium hardness | 3 min | Especially well water |
| Check stabiliser level | 3 min | If using stabilised chlorine |
| Filter backwash | 10 min | If pressure +0.5 bar |
| Clean salt cell | 20 min | If electrolysis |
| Check covers/rollers | 5 min | General condition |
Waterline
Why it's important:
- Accumulates oils and dirt
- Can form scale
- Affects pool aesthetics
How to clean:
- Specific descaling product
- Non-abrasive sponge
- Rinse well
💡 Dica Profissional
In condominium pools or those with heavy use, the waterline should be cleaned weekly. Sunscreen and cosmetic oils accumulate quickly and become harder to remove over time.

Frequently Asked Questions
Can I reduce maintenance in winter?
Yes, but not eliminate it. In winter, frequency can reduce to about 50% of summer, but the water still needs treatment to avoid problems in spring. Weekly pH and chlorine tests are the minimum recommended.
Does a robot replace manual maintenance?
Partially. The robot does automatic vacuuming, but you still need to manually brush walls, clean the waterline, test and treat the water. A robot reduces work by about 30-40%, it doesn't eliminate it.
How much time per week should I dedicate to the pool?
For a typical residential pool:
- Summer: 2-3 hours/week
- Rest of year: 1-1.5 hours/week
With a robot and good automatic dosing system, you can reduce to 1-2 hours/week in summer.
Is a maintenance contract worth it?
It depends. For those without time or who don't want to learn, yes. A typical contract costs €100-200/month and includes weekly or fortnightly visits. For those who enjoy maintaining their own pool, product costs are usually €30-50/month.
Conclusion
The ideal maintenance frequency depends on various factors, but the basic principles are:
- Check daily water appearance and level
- Test 2-3 times/week pH and chlorine (more in summer)
- Clean weekly floor and walls
- Inspect monthly equipment
- Do preventive maintenance quarterly/six-monthly
- Professional service annually recommended
The main points to remember are:
- Consistency is key – regular maintenance prevents problems
- Adapt to season – more frequent in summer
- Know your pool – each has particularities
- Keep records – helps optimise frequencies
- Prevention is cheaper – than cure
