Why use TH+?

TH+ powder is a calcium chloride-based product that quickly increases the TH of the water. The TH (Hydrotimetric Title) of swimming pool water is an important parameter that measures the hardness of the water, i.e. its content of dissolved calcium and magnesium salts. A balanced TH will contribute to a more stable pH and better protection of swimming pool installations.

What is TH?

The TH or Hydrotimetric Title corresponds to the hardness of the water, which designates its concentration in limestone.

Use it with app

You can free download our application on Apple Store (IOS) or Play Store (Android). Then you can follow advice from our recommendation engine to know when and how you can use our chemicals products.

How it works

By being released in contact with your swimming pool water, iopool's TH+ releases calcium and magnesium ions, increasing the hardness of the water.

Main advantages

  • High TH+ concentration;
  • High-grade quality TH+;
  • A small amount of dust;
  • Fast efficiency;
  • Compatible with all treatments;
  • Compatible with all filtration systems.

Usage advice

  • Activate the filtration of your swimming pool;
  • Dilute the TH+ in a bucket of water;
  • Disperse the mixture of water and TH+ in your swimming pool.


  • A low total hardness may damage the liner and the plastic elements of the swimming pool;
  • A high total hardness may cause lime deposits to form on the waterline, the filtration system, and your equipment.
