A UV device can be used to complement your filtration system to combat green water. The filter will tend to combat brown water and organic pollution in the pool. These UV devices remove micro-algae and germs present in the water.

How to choose a UV lamp for my garden pond? For a filter, we choose it according to the quantity of water present in the pond, the sunshine, and the quantity of fish. For the UV filter, we advise you to respect a minimum of 3W/1000L of water.

EX: your pool is 2000L, you will be able to choose a 7W UV. If you opt for an 18W, you will change the lamp half as often. Indeed, a UV loses on average 50% of its power per 6-month season. If your pool is exposed to full sun, choose a more powerful UV filter.

The lamp is a consumable that has a lifespan of 5000 to 7000 hours depending on the model. A full pool season represents on average 6000 hours. Be careful, even if your bulb still lights up, it is not necessarily efficient. Its radiation decreases with the hours of use.

Also make sure to maintain the QUARTZ which tends to fill up with limescale. We clean it with products such as vinegar or OPTINET . Be careful to rinse well before restarting.

To choose a UV lamp suitable for your pool, we advise you to always take a lamp a little more powerful than expected. For example, if you have a pool of 11M³ and you install a 36W lamp (3W per M³ of water). A UV loses 30 to 40% of its power per year. As a result, you may have to change your UV lamp every year. If you choose a 55W lamp, you are in for 2 to 3 years. Do you need help? Contact our team who will be happy to advise you on choosing a UV lamp suitable for your pool.

FAQ:

Claude: " Will the 36W vitronic uv be enough for my 11m3 pool? "

For a pond of 11 m³, the Oase Vitronic 36W should be sufficient, but this also depends on some factors such as sun exposure, fish population density and water quality. As a rule of thumb, the Vitronic 36W is effective up to 12M³.

If Claude has a recurring problem with algae, he can also consider a complementary treatment such as Aquipond Greenstab, in addition to the UV system.
