How to choose

**Setting up a garden pond:**

1. **Liner sizing** — calculate liner size as: (length + 2×depth + 0.6m) × (width + 2×depth + 0.6m). Always buy slightly larger than calculated.
2. **Pump selection** — the pump should circulate the full pond volume once per hour. For a 1,000L pond, choose a minimum 1,000 L/h pump.
3. **Filtration** — UV clarifiers kill algae; biological filters process ammonia from fish waste. Both are essential for fish ponds.
4. **Pond netting** — install in autumn before leaves fall. Fine-mesh nets also deter herons from taking fish.
5. **Water treatment** — dechlorinate tap water before filling. Test and treat water chemistry before introducing fish.
Trade Tip

**Trade tip:** When installing a pond for a customer, fit the pump with a standard-sized connector rather than a permanent fitting — this allows the customer to replace the pump themselves without needing a contractor for a straightforward maintenance task. It reduces callback calls significantly.

Frequently Asked Questions

How do I choose the right pond liner?

Butyl rubber liners are the most durable (25+ year lifespan) but more expensive. PVC liners are budget-friendly and suitable for smaller ponds. EPDM liners offer a balance of cost and durability.

How often should I run my pond pump?

Continuously for fish ponds — stopping the pump depletes oxygen levels rapidly. For ornamental ponds without fish, the pump can be run on a timer, but aim for at least 12 hours per day.

What causes green pond water?

Green water is caused by suspended algae, typically triggered by high nutrient levels (fish waste, leaf debris) and sunlight. A UV clarifier combined with a biological filter resolves most cases within 1–2 weeks.
