Delphin Spa Alkalinity Up
To increase the alkalinity of the bath water, you can use Alkalinity Up because Alkalinity helps you to keep the pH of the spa water stable.
Low alkalinity causes metal to rust in the water and produces large deviations in pH control. Alkalinity Up acts as a pH brake in the water, making it much easier to control the pH value.
Instructions for use Alkalinity Up:
Alkalinity is measured with a pool tester/test strips. Your pH value should be between 7.0-7.4 because then the water feels nice and comfortable when you bathe. Alkalinity should be between 80-120 mg/l.
To increase alkalinity by 10 ppm add 20g (4 teaspoons) of Spa Alkalinity Up per 1000 litres of water.
basic advice:
- When adding new water to the spa, start by measuring the pH balance. Always try to be in the range of 7.0 - 7.4. The alkalinity should be 80-120 mg/l. If it is too low, add Alkalinity Up.
- Use chlorine as a disinfectant in your spa. Cheapest and best. If you are allergic to chlorine, use Bromine.
- Do not underdose. Don't be afraid of the chlorine, be afraid of the bacteria. Always dose according to the instructions on the package.
- Make sure you take a good shower before bathing and thoroughly rinse off any soap residue on your body and swimwear.
- Feel free to use Cleaning-free spa filters which keeps the water cleaner and makes it easier to care for your spa.
- Change the water in the spa 3-4 times per year and at the same time clean the pipework with a special "pipe cleaner".
- When changing the water, it is also advisable to clean the spalocket and treat the vinyl against weather, wind and UV radiation.
A very important rule for good and clear bathing water is to shower thoroughly before bathing. An unshowered person carries 200 times more pollution than a showered person.
