Why use ALKA+

ALKA+ (also known under the TAC+ denomination) helps to stabilize the chemical reactions of water between products (eg: acid/base balance).

Alka+ is the perfect product for anyone looking to stabilize the chemical reactions of their water. It increases the alkalinity of the water and helps to ensure that your water is always in the perfect pH range for maximum productivity and performance. It is the ideal solution for any environment requiring clean and safe water.

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

The ALKA is a measure that tells you the number of mineral salts present in the water. The alkalinity of water determines the "buffering" power of water. An ideal rate makes it possible to stabilize the chemical reactions between the maintenance products and the water in your swimming pool. By releasing it into the water, our Alkalinity Booster will increase the alkalinity of your water without adding unwanted chemicals.


Main advantages

  • High ALKA+ concentration ;
  • Quality/price ratio;
  • High grade ALKA+ quality ;
  • Treatment efficiency;
  • No residue.
  • Compatible with all treatments.
  • Compatible with all filtration systems.

Usage advice

  • Check if pH is between 7.2 and 7.6;
  • Activate the filtration of your swimming pool;
  • Dilute the ALKA+ in a bucket of water;
  • Disperse the mixture of water and ALKA+ in your swimming pool.


  • Ideal concentration: between 80 and 150ppm and preferably close to 150ppm;
  • Go gradually and never overtake 500g ofALKA+ for 10m³ of water in one time;
  • Be careful, increasingALKA will equally increase pH. Lower is the ALKA concentration, more the pH concentration gonna reduce fast when adding acidity (pH+).;
  • Too much ALKA can cause milk water and tartar deposits.

Produit Alka+

Jusqu’à présent je n’ai pas utilisé ce produit car je n’en avais pas eu besoin. La qualité de l’eau a été stabilisée avec le Chlore et le PH+

Excellente qualité et efficacité

troisième achat de ce produit chez iopool. Très efficace et excellent rapport qualité/prix par rapport aux produits de chez Brico
