“The biofilm serves as a “refuge and sanctuary” and protects the bacteria from the disinfectant. Lotus Clean Shock is the only disinfecting product that penetrates the biofilm and destroys the polysaccharides (complex sugars) contained therein.”

• After the first filling of the spa.
• If the water is not crystal clear.
• If the water smells unpleasant.
• If you have greasy deposits on the sides of the spa.
• If the water is very dirty after a „spa party“.
• Periodically, when using disinfectants such as chlorine, bromine, active oxygen, etc.

It is also possible to disinfect the spa with Lotus Clean Shock only. This is recommended, for example, for wooden hot tubs without a filter system.

Add 50 ml Lotus Clean Shock per 1000 litres of water content to the water. When adding Shock, let the pumps run for better mixing. It is important that Lotus Clean Shock can work for at least 8 hours. (If it works for less than 8 hours, there may still be bacteria and dirt in the spa).

You can control the concentration of Lotus Clean Shock with the Lotus Clean Test Stripes. After 8 hours, the Test Stripes should still show at least 1 ppm concentration. If there is no more Shock in the water before the 8 hours have elapsed, repeat the shock treatment. Important: These values refer to 37 degrees Celsius warm water. With colder water, Shock degrades slower.

If Lotus Clean Shock still degrades too quickly after the second use, this may indicate heavy soiling with a lot of biofilm in the pipes.

Carry out a Shock Cleaning. The instructions can be found on our website. If this also does not help, you will have to carry out an Intensive Cleaning. You can also find all information on this on our website.
