Introduction
Going on summer holiday and leaving the pool behind can be a source of worry. Warm water, absence of regular maintenance and intense heat can transform a crystal clear pool into a green problem in just a few days.
In Margem Sul, where summer is particularly hot and dry, the challenge is even greater. But with proper preparation, it's possible to go on holiday peacefully and return to a pool in good condition.
This guide covers all strategies to prepare, maintain and recover your pool before, during and after summer holidays.
Before You Leave
How Far in Advance
| Holiday Duration | Preparation Needed |
|---|
| 3-5 days | 1 day before |
| 1 week | 2-3 days before |
| 2 weeks | 1 week before |
| 3+ weeks | Consider professional help |
Deep Cleaning Beforehand
| Task | Importance |
|---|
| Vacuum floor completely | Removes organic matter |
| Brush all walls | Eliminates early algae |
| Clean waterline | Prevents build-up |
| Empty skimmers and baskets | Maximum capacity |
| Filter backwash | Efficient filtration |
Balance the Water
| Parameter | Value Before Leaving |
|---|
| pH | 7.2-7.4 (ideal 7.2) |
| Chlorine | 3-5 ppm (slightly high) |
| Alkalinity | 100-120 ppm |
| Stabiliser | 40-50 ppm |
💡 Dica Profissional
Leave chlorine at the upper limit (3-5 ppm) before departing. During your absence, it will naturally drop, and starting high gives a safety margin.
Maintenance Options During Absence
Option 1: Self-Maintenance (up to 1 week)
| Preparation | Procedure |
|---|
| Shock treatment | Do 24-48h before leaving |
| Chlorine tablets | Add extra quantity |
| Long-lasting algaecide | Preventive dose |
| Flocculant tablets | In skimmer |
| Pump timer | Programme 10-12h/day |
Advantages:
- No additional costs
- Total autonomy
Disadvantages:
- Risk if extended holidays
- No supervision
- Depends on weather
Option 2: Trusted Neighbour/Family Member
| Task to Delegate | Frequency |
|---|
| Check water appearance | Daily |
| Test pH and chlorine | 2-3x week |
| Add chlorine if needed | Per test |
| Collect leaves | Daily |
| Check equipment | Daily |
Instructions to leave:
- Ideal pH and chlorine levels
- Where products are stored
- How much to add of each
- Emergency number
- Don't touch unknown equipment
Option 3: Professional Service
| Service | Typical Frequency |
|---|
| Maintenance visit | 1-2x per week |
| Complete analysis | Each visit |
| Chemical adjustment | Each visit |
| Basic cleaning | Each visit |
| Status report | By email/SMS |
Advantages:
- Total peace of mind
- Professional expertise
- Response to problems
Disadvantages:
- Additional cost
- Needs property access
💡 Dica Profissional
For holidays longer than one week in Margem Sul, a professional service is highly recommended. The intense heat can rapidly degrade an unsupervised pool.

Frequently Asked Questions
Can I cover the pool during holidays?
You can, if you prepare well first (cleaning, treatment, high chemicals). The cover reduces evaporation and debris entry. Use a cover that allows minimal light passage to prevent algae.
What do I do if the pump breaks down during holidays?
If someone checks daily, they can call a technician. If no one is there, damage can be significant. Consider having an electrician/technician contact available for whoever is watching.
Should I lower the water level before leaving?
Not normally. Evaporation is high in summer and a low level can cause problems with skimmers. On the contrary, fill slightly above normal.
How long can a pool last without maintenance in summer?
Depends on conditions, but typically 3-5 days with proper preparation. Beyond a week without any maintenance, the risk of serious problems is very high in Margem Sul.
Is it worth hiring a professional service just for holidays?
Yes, especially for holidays longer than one week. The cost (€100-150 for 2 weeks) is much less than the cost of recovering a pool with severe algae or equipment damage.
Conclusion
Peaceful holidays with a pool at home are possible with the right preparation:
- Prepare in advance (cleaning, chemicals, equipment)
- Automate what you can (filtration, dispensers)
- Delegate if possible (neighbour, professional)
- Communicate clear instructions
- Check immediately upon return
- Act quickly if there are problems
The investment in preparation or professional service is always less than the cost of recovering an abandoned pool.
