Filter Clean 1 liter

Effective special agent for cleaning cartridge filters and diatomite filters. Removes dirt, grease, soap residue etc.
Filter cleaning helps the filter system work efficiently. By regularly cleaning the filter, you also increase the conditions for optimal water quality.
Works together with disinfectant products such as chlorine, bromine, active oxygen and biguanide.
Add 2 cups of filter cleaner per 10 liters of water in a bucket. Place the filter cartridge upright in the bucket so that the entire cartridge is covered with water. Allow to work for at least 3 hours, preferably overnight if possible.
Rinse the cartridge thoroughly with a strong jet of water.
We recommend letting the cartridge dry completely before brushing it off and putting it back in the spa.
Never add filter cleaner to the water in the spa!
