# HOW NATURAL POOLS WORK

## Biological Filtration Explained

Natural swimming pools use living systems instead of chemicals to keep water clean. This is the same process that keeps lakes and rivers pure.

### The Two-Zone System

**Swimming Zone:**
- Clear, deep water for swimming
- No plants (unobstructed swimming)
- Depths of 1.5-2.5 metres
- Smooth, comfortable surfaces

**Regeneration Zone:**
- Shallow planted area (typically 0.3-0.6m deep)
- Contains aquatic plants that filter the water
- Beneficial bacteria break down organic matter
- Gravel substrate for biological filtration
- Should be 30-50% of total pool area

### How Water Gets Clean

1. **Circulation**: Low-energy pump moves water between zones continuously
2. **Nutrient absorption**: Plants absorb nitrogen, phosphates, and organic debris
3. **Bacterial action**: Beneficial bacteria break down organic matter
4. **Oxygenation**: Plants release oxygen, keeping water fresh

### Why It Works

- Self-regulating ecosystem
- Adapts to seasonal changes
- No chemical side effects (red eyes, dry skin, bleached swimwear)
- Water quality often exceeds EU bathing standards

# REGENERATION ZONE GUIDE

## Sizing Your Regeneration Zone

The regeneration zone is crucial for water quality. Size it correctly and your pool will stay crystal clear.

### Recommended Ratios

| Climate/Usage | Regeneration Zone Size |
|---------------|----------------------|
| Light use (occasional swimming) | 30% of total area |
| Moderate use (regular family swimming) | 40% of total area |
| Heavy use (daily swimming, parties) | 50% of total area |

### Example Calculations

**50m² total pool area with moderate use:**
- Swimming zone: 30m² (60%)
- Regeneration zone: 20m² (40%)

**80m² total pool area with heavy use:**
- Swimming zone: 40m² (50%)
- Regeneration zone: 40m² (50%)

### Design Options

**Surrounding design**: Regeneration zone wraps around swimming area
- Pros: Integrated look, easy access for maintenance
- Cons: Takes more total space

**Side-by-side design**: Zones next to each other
- Pros: Space efficient, clear separation
- Cons: More visible infrastructure

**Remote design**: Regeneration zone separate from swimming area
- Pros: Maximum swimming space, hide the "working" zone
- Cons: More pipework, higher pump costs

- Often lower cost (£60,000-£100,000)
- More "wild" aesthetic

### Natural Swimming Pool
- Can be contemporary or formal
- Geometric shapes possible
- Clean architectural lines
- Separated swimming/regeneration zones
- Often higher cost (£90,000-£200,000+)
- More "designed" aesthetic

### Same Principles
Both use identical biological filtration:
- Aquatic plants filter water
- Beneficial bacteria break down organics
- No chemicals required
- Crystal-clear swimming water

# COMMON MISTAKES TO AVOID

## Learning from Others' Errors

### Design Mistakes
1. **Undersized regeneration zone**: Leads to water quality issues
2. **Poor circulation design**: Dead spots develop algae
3. **Wrong plant selection**: Non-native or unsuitable species
4. **Inadequate access**: Can't maintain the pool properly
5. **Ignoring sun exposure**: Too much shade = poor plant growth

### Construction Mistakes
1. **Cheap liner**: Fails within years, costly to replace
2. **Undersized pump**: Water doesn't circulate adequately
3. **Poor edge detail**: Allows water behind liner
4. **No overflow system**: Flooding in heavy rain
5. **Rushed planting**: Ecosystem takes time to establish

### Maintenance Mistakes
1. **Over-cleaning**: Removing beneficial bacteria
2. **Adding fish**: Nutrients cause algae problems
3. **Fertiliser near pool**: Runoff feeds algae
4. **Neglecting autumn cleanup**: Leaves rot in winter
5. **Draining for winter**: Damages liner and ecosystem

# FREQUENTLY ASKED QUESTIONS

## General Questions

**Do natural pools work in the UK climate?**
Yes! Natural pools thrive in the UK. The cooler climate actually helps prevent algae. Most owners swim from May to October, and heated pools extend the season to April-November.

**How long does installation take?**
Typically 8-16 weeks depending on size and complexity. The best time to start is autumn for a spring/summer completion.

**Do I need planning permission?**
Usually no, if the pool is within your garden boundary and doesn't alter land levels significantly. Conservation areas, listed buildings, and AONBs may require permission.

**How do natural pools stay clean without chlorine?**
Aquatic plants and beneficial bacteria in the regeneration zone naturally filter the water. It's the same process that keeps lakes and ponds clean.

**Can I have fish in my natural pool?**
We don't recommend it. Fish waste adds nutrients that can cause algae. A separate wildlife pond is better if you want aquatic life.

**What about safety?**
Natural pools meet the same safety standards as traditional pools. Water quality typically exceeds EU bathing water standards.

**How much does a natural pool cost?**
Starting from £65,000 for a swimming pond, £90,000-£150,000 for a standard natural pool, and £150,000+ for premium installations.

**What are the running costs?**
Annual running costs are typically £700-£1,500 compared to £2,000-£3,500 for chlorinated pools. No chemicals needed.

**Do natural pools attract mosquitoes?**
No. The constant water circulation prevents mosquito breeding, which requires still water. Dragonflies and frogs also help control insects naturally.

**Can I swim all year round?**
Without heating, the comfortable swimming season is May-September. With a heat pump, this extends to April-October. Cold water swimming enthusiasts use natural pools year-round.
