Alka Reef+ maintains optimum levels of alkalinity in reef aquariums by supplying carbonate ions.

Helps to reduce the unwanted pH variations

Contains carbonate ions to maintain your aquarium at its optimum alkalinity level

It works with Calci Reef+, a calcium hydro-gel that slowly releases hydrogen carbonate ions into the water.

Alka Reef+ is gluconate free

In addition to carbonate ions (with Calci Reef +), the calcification reaction also uses up calcium

When should Alka Reef+ be used ?

When you have unwanted pH variations in your saltwater aquarium

The combination of Alka Reef+ and Calci Reef+ generates an ionic balance close to that of natural sea water in your tank

We therefore recommend that you add one ampoule of Calci Reef+
