Easy water hygiene with Kirami

Easy water hygiene with Kirami | Kirami


Many of the questions we receive about our hot tubs are related to water hygiene. A lot of people seem to think that taking care of water hygiene is difficult. In reality, it’s quite easy to keep your bathwater clean, as long as you have good instructions. When you follow Kirami’s advice, your bathwater will stay clean.


A tip for using the tub at your cottage: bathe throughout the weekend with a single fill

The water maintenance required by a hot tub depends on where the tub is used. At a summer cottage, where bathwater is often carried from the sea, a river or a lake, the water may be changed for each bath. This way, you will always have clean water, although the constant filling and emptying of the tub takes some effort. When using sea and lake water, it is good to be especially careful about a water hygiene and we always recommend the use of chemicals. Well or tap water you can bath through the weekend without a filter, but chemicals are good to use.

If you wish to bathe in the same water for 1–3 times, for example for the entire weekend, you should use one of the following options.


For gradual and even cleaning:

Kirami offers Biocool water treatment product, Biocool Disinfect my pool (1000 ml) for water purification which is suitable for continuous disinfection. Active oxygen or multi-function tablets can also be used for permanent disinfection. You can ask more information about your closest reseller.

  • Biocool Disinfect my pool provides gentle, simple and effective products for clean water and healthy skin. Biocool Disinfect my pool is odourless and chlorine-free. The product is biodegradable. With the help of the dosing module, dosing is made simple and occurs directly from the bottle. The product is a novelty for summer 2020.
  • Please note: If you are using active oxygen or multi-function tablets, do not place the tablets directly into the tub. Instead, they need to be placed in a dispenser where they will float into all parts of the tub along the water. Don’t forget to remove the dispenser from the water for the duration of the bath.


For quick cleaning: Shock treatment destroys bacteria

For immediate disinfection effect use dissolving chlorine or active oxygen granules.

  • Please note: Remember to mix the granules with a small amount of water before putting them into the tub.


Water from a tap or a well? How to keep your water clean throughout the summer

If you need to fill your tub with tap water or well water, it will be worth it to invest in thorough water hygiene. When the water is maintained properly, it will remain clean and pleasant for a long time, even throughout the summer. This type of water maintenance is not very complicated, either. Kirami recommends using a filter system and chemicals either with or without chlorine. 


Filters and chemicals take care of water hygiene

Bathwater maintenance consists of two areas: mechanical sanitation with a filter and chemical cleansing with cleaning agents. A filter in the tub removes loose dirt from the water, and the cleaning chemicals mixed into the water remove bacteria and algae.

When purchasing the chemicals, you need to decide if you want to clean your tub with chlorine, active oxygen or Biocool. Chlorine is a common cleaning agent used in places such as public swimming pools because of its powerful and long-lasting effect. However, not everyone wants to use chlorine due to sensitivity and allergies. In this case, cleaning your tub with active oxygen or Biocool is a viable alternative. If there are multiple bathers or if the tub is in public use, we strongly recommend the option with chlorine

Fix your tub’s pH values

First, you need to ensure that the pH value of the bathwater is at a correct level so that the cleaning chemicals will work in the best possible manner and that heater won’t be corroded. Using pH test strips is the easiest way to check the pH value. A strip is dipped into the tub, after which you can compare the colour of the strip to the colours on the can. A more precise pH measurement can be made with a pH tester than can also be used to check the oxygen content and the amount of free chlorine in the water. The testing tablets are placed in the compartments of the tester, and water is scooped from the tub into the test box. As the tablets dissolve, they dye the water in the tester. The scale on the side of the tester shows which colour corresponds to which pH value. The ideal pH value is 7.0–7.4. If the pH value is under the ideal level, pH+ granules, in the amount specified in the instructions, are first added into the bathwater, taken from the tub, in a separate bucket. Once the granules have dissolved, the water in the bucket is poured back into the tub. If the pH value is too high, the same procedure is performed using the pH- granules.

In a nutshell: keeping your bathwater clean and pleasant only requires a few steps. First, you measure the condition of the water, and then you improve it with pH granules and cleaning tablets.



Biocool Disinfect my pool provides simple and effective disinfection of pool water and is biodegradable. No complementary products are required, although in certain cases it may be necessary to also use the flocculating agent Biocool Clear my pool water to ensure that small particles in the pool water can more easily be captured by the pool’s filter. The product works at various pH values without losing effectiveness, which eliminates the need to perform a measurement of the pool water’s pH value. With the help of the dosing module, dosing is made simple and occurs directly from the bottle, which makes this product significantly easier to use and handle than conventional methods. 

Note! For quick cleaning, you can first use Shock Chlorine!
