Fresh and clear water thanks to proper hot tub water maintenance

So that you can enjoy clean and clear hot tub water for a long time, it's essential to pay attention to maintenance. Below you'll find our tips for enjoying fresh and clean water for longer.

Chlorine and other maintenance products

Chlorine and other maintenance products play an important role in keeping hot tub water clean and safe. Chlorine ensures that bacteria, algae and other contaminants are killed, while additional products help keep the water balance stable. Think of products for correcting the pH value and removing metals. By using these maintenance products correctly and regularly, the water stays clear, fresh and comfortable to relax in.

Filter system

A properly functioning filter system plays a crucial role in keeping hot tub water clean and clear. The filter removes dirt, skin residue, oils and other contaminants that enter the water during use. Without effective filtration, these particles keep circulating, causing the water to become cloudy faster and reducing the effectiveness of chemicals. In addition, the filter supports the action of chlorine and other maintenance products by keeping the water in continuous motion.

Backwash filter system

It's best to backwash based on the pressure on the filter manometer. Note the pressure right when you first use the filter and after you've backwashed. Once the pressure has risen by about 0.7 bar, it's time to backwash. If you don't do this in time, the filter becomes increasingly clogged as all the dirt particles remain, making water flow more and more difficult. As a result, the filter system works much less efficiently, the pressure in the system can rise, and you'll ultimately get poorer filtration of your hot tub water, which can lead to poor water quality.

Hygiene

Showering before getting into the hot tub is a small effort, but it makes a big difference to water quality. By rinsing off, you remove sweat, body lotion and deodorant. This means chlorine has to work less hard, keeping the water clean and clear for longer. It also helps prevent cloudy water, foaming and unpleasant odours faster. In addition, your filter and cover stay in better condition for longer, since less dirt and grease builds up.
