Alkalinity after rainfall
Rain is a good reason to check the alkalinity of the pool water. After the heavy rain showers we have experienced this summer, the water's alkalinity will be close to 0 - it is important for having clean and good pool water to get this in order
The large amounts of precipitation that we have experienced several times in recent years lower the alkalinity in many outdoor swimming pools and hot tubs each time. It is the torrential rain that causes this problem.
When we subsequently measure customers' water from outdoor swimming pools, the alkalinity values show < 20 mg/l and in some cases all the way down to 0, where the correct level is 80-120 mg/l.
Pool and spa owners will have problems controlling the pH value and will therefore experience algae growth, limescale deposits and generally reduced water quality. It would be a very good idea to have the alkalinity checked. You do this best with a Smarttester from Lovibond, which you can find in our webshop here and adjust it with Saniklar Alka Plus or SpaCare Alka Up.
If alkalinity is <50 mg/l, you should adjust with Alka Plus/Up.
- Measure the water's alkalinity with an alkalinity tester and regulate if necessary to a level of 80 - 120 mg/l.
- To raise the alkalinity by 10 mg/l in 20 m³ of water, add 350 g Alka Plus = 2½ dl.
You can enter your measurements in our calculator, which you will find under the Saniklar Alka Plus product
