Who doesn't dream of clear, limpid water for their garden pond?

A UV device can complete your filtration system to fight against green water. The filter will tend to fight against brown water and organic pollution in the pond. These UV devices remove micro-algae and germinate present in the water.

How do I choose a UV lamp for my garden pond? For a filter, it is chosen according to the quantity of water present in the basin, 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 UV of 7W. 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 season of 6 months. If your pool is exposed to full sun, choose a more powerful UV filter.

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

Also be sure to properly maintain the QUARTZ which tends to fill with limestone. We clean it with a product such as vinegar or OPTINET . Be careful, rinse well before restarting.

To choose a UV lamp suitable for your pool, we advise you to always take a lamp that is a little more powerful than expected. For example if you have an 11M³ pool and you place 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 therefore left for 2 to 3 years. You need help? Contact our team who will be happy to advise you on choosing the right UV lamp for your pool.
