How to choose your pond UV filter?

It is essential to choose a UV device adapted to your pond: volume of water, exposure and quantity of fish (or swimmers) depending on the type of pond.

1. Understanding the Usefulness of a UV Device

A UV (ultraviolet) device is used to sterilize your pond water by killing algae, parasites, and harmful bacteria. This helps keep the water clear and healthy for fish and plants.

This device emits UV-C rays that will eliminate micro algae suspended in the water that can make the water green. These devices are generally connected between the pump and your pond filter, except in a pressure installation where the UV-C is often installed after the pressure pump.

2. Calculate the Volume of Your Pelvis

Before choosing a UV device, it is important to know the volume of your pond. Here is how to calculate it. If you have any questions, contact us via support@aquiflor.com; we will be happy to help you choose a suitable UV-C device. We also have telephone support at 003210860354. Here are the simple formulas to calculate your water volume:

Rectangular/Square Shape:
$𝑉 𝑜 𝑙 𝑢 𝑚 𝑒 (𝑙 𝑖 𝑡 𝑟 𝑒 𝑠) = 𝐿 𝑜 𝑛 𝑔 𝑢 𝑒 𝑢 𝑟 (𝑚) \times 𝐿 𝑎 𝑟 𝑔 𝑒 𝑢 𝑟 (𝑚) \times 𝑃 𝑟 𝑜 𝑓 𝑜 𝑛 𝑑 𝑒 𝑢 𝑟 (𝑚) \times 1000$
Circular Shape:
$𝑉 𝑜 𝑙 𝑢 𝑚 𝑒 (𝑙 𝑖 𝑡 𝑟 𝑒 𝑠) = 𝜋 \times (𝑅 𝑎 𝑦 𝑜 𝑛 (𝑚))^{2} \times 𝑃 𝑟 𝑜 𝑓 𝑜 𝑛 𝑑 𝑒 𝑢 𝑟 (𝑚) \times 1000$ $𝜋 \approx 3.14$

3. Choose the Power of the UV Device

The power of the UV device is generally expressed in watts (W). Here is a general rule for choosing the power according to the volume of your pool:

Small ponds (up to 5,000 litres): 10-20 watts
Medium ponds (5,000 - 10,000 litres): 20-50 watts
Large pools (10,000 - 20,000 liters): 50-100 watts
Very large pools (20,000 liters and more): 100 watts and more

4. Consider the Pump Flow Rate

For the UV device to be effective, it must be compatible with the flow rate of your pond pump. The ideal flow rate is one that allows the water to pass slowly enough through the UV device to be well exposed to the UV rays. Here are some recommendations:

Recommended Flow Rate: Pond water should pass through the UV unit approximately once every 2 hours.
Flow Calculation: $𝐷 \overset{ˊ}{𝑒} 𝑏 𝑖 𝑡 (𝑙 𝑖 𝑡 𝑟 𝑒 𝑠 / ℎ 𝑒 𝑢 𝑟 𝑒) = 𝑉 𝑜 𝑙 𝑢 𝑚 𝑒 𝑑 𝑢 𝑏 𝑎 𝑠 𝑠 𝑖 𝑛 (𝑙 𝑖 𝑡 𝑟 𝑒 𝑠) / 2$

5. Check Quality and Sustainability Criteria

When you are going to choose a UV device, make sure that it is of good quality and durable. Check the following points:

Brand and Reputation: Favors brands that are recognized and well rated by users.
Materials: Choose materials that are water and weather resistant.
Warranty: A 1-2 year warranty is often a good indicator of quality.

6. Installation and Maintenance

Installation: Follow the manufacturer's instructions carefully for installation. Typically, the UV unit should be placed after the mechanical filter.
Maintenance: Replace the UV lamp every 6 to 12 months to maintain optimal effectiveness.

Conclusion

By following these simple steps, you can choose a UV device that is suitable for your garden pond and ensure clear and healthy water for your fish and plants. Do not hesitate to consult a
