Kalk-Ex prevents calcium deposits on the walls and in the pipes of your spa.    

• Chlorine stable, pH neutral

• phosphate-free

• Prevents the precipitation of hardness agents and thus the formation of water turbidity and limescale deposits

• Binds metals in the water, preventing water discoloration by metal ions    

Alka-Plus increases the alkalinity of your spa water. A too low alkalinity can cause the pH to fluctuate greatly during adjustment, making adjustment difficult. Furthermore, the water can become corrosive, resulting in surfaces such as e.g. can attack the whirlpool tub.

• Prevents damage to surfaces and fittings

• Stabilizes the pH and makes the adjustment easier

For measuring pH, chlorine / bromine, active oxygen, alkalinity (TA) and total hardness    

• Measures 5 parameters with only one strip

• Easy to use

• No handling with reagents or test tablets necessary

• Results easily and immediately readable
