Lotus Clean water care instructions

Lotus Clean water care can vary between different types of whirlpools. There are several factors that determine this: water volume, temperature and filtration. We distinguish between hard shell spas, inflatable spas / softubs and SwimSpas. Please refer to the dosage quantities according to your spa type.

Water Care Instructions

Instructions For Refilling

1) Fill your spa with water
2) Add Calcium Ex and Lotus Clean Shock
3) Check pH value, adjust if over 8

1) If the water is clear and odourless, you can bathe from now on
2) Add Lotus Clean Basic in the evening
3) Check pH value, adjust if over 8

DAY 3-6
1) Check pH value, adjust if over 8
2) After a bath, add 5ml of Lotus Clean Shock per person into the water (at least 10ml per bath)

Check pH value and clean filter.

There should always be 0.3 mg/l Lotus Clean Shock in the water during the first two weeks. Measure one day after adding.

Instructions Regular Operation

  • After a swim, add 5ml of Lotus Clean Shock per person into the water (at least 10ml per bath)
  • Once a week: Check pH value, clean the filter and add Basic and Shock
  • Dose Calcium Ex monthly: 50ml/1000l and proportionally if you refill with water 
  • Every 6 months, at the latest every 12 months: Perform basic cleaning with System Wash and change the water

There should always be at least 3 hours between the addition of Lotus Clean Shock and Lotus Clean Basic.

General Information about disinfection, limestone, pH value and filter cleaning

Lotus Clean Basic encapsulates bacteria and dirt. The filters help you to remove the encapsulations from the pool. Shock is especially effective against biofilms and kills bacteria, viruses and fungi.

During the first 2 weeks there should always be at least 0.3 mg/l Lotus Clean Shock in the water. Measure the day after the addition. If your water becomes cloudy, the Shock dosage must be increased again so that 0.3 mg/l Shock is present in the water. Repeat this process until the water remains crystal clear and odourless during the regular weekly addition of Shock.

The harder the water, the more lime it contains. If lime precipitates, it will settle on the shell and in the pipes. Then it is a basis for biofilms and makes water purification more difficult. Limestone precipitation is related to the pH of the water. This is why the pH value should always be between 6.5 and 7.8. With pH values above 8.0, lime precipitation can occur. Check the pH value 1-2 times a day for a new filling and once a week for regular use.

How do I regulate the pH value?
First measure the pH value. Then add about one tablespoon of pH-Minus to the water. Let the pumps run for about 5 minutes. Measure the pH value again 2 hours later. From the difference to the first measurement you can estimate how much pH reducer you still have to add to the water.

Please Note:
In the first few days, the pH value can quickly rise very high. In this case it may be necessary to adjust the pH value twice a day.

Filter cleaning
The filters collect suspended particles and the gel that Lotus Clean Basic forms by encapsulation. Without cleaning, the filters will clog and make water cleaning more difficult. The filters should be cleaned with a filter spray and filter cleaner, e.g. Filter Wash Natural. When refilling, the filters should be cleaned 1-2 times a week. In regular operation one cleaning every 1-2 weeks is sufficient.
