Swimming pool and other recreational water depends both on alkalinity and pH to maintain the balance needed for sanitizers to work and swimmers to enjoy their time in the pool.

FMC’s Pool Grade sodium bicarbonate offers customers the alkalinity and pH adjustment necessary to maintain healthy water.

Sesqui^TM sodium sesquicarbonate provides this balance in a single treatment product. How? By working on both pH and alkalinity at the same time. Sesqui^TM does this by combining the alkalinity reserve of sodium bicarbonate and the pH increasing power of soda ash. It provides this combination in a pure, sparkling white product that is safe and easy to use. Sesqui^TM is two products in one.

Chemically speaking, Sesqui^TM sodium sesquicarbonate is a distinct alkali product built by linking one part of sodium bicarbonate (for alkalinity control) with one part of soda ash (to increase pH). It's able to lock in alkalinity because of its buffering power and it can neutralize the acid introduced from sanitizers, swimmer load, or even rain and dirt in the water. Water gets the right pH with one treatment; the first time and every time!

What's more, Sesqui^TM is a single crystalline material, not a mix or a blend. That means it's uniform, easy to handle and pour, and won't separate during use. Sesqui^TM is already hydrated, so it dissolves easily and it's less prone to lump up during storage. Adding Sesqui^TM to a pool is a snap - it dissolves rapidly, lessening the chances of pool clouding and making for trouble-free application.

Look to Sesqui ^TM as your one-step solution for pH and alkalinity control.
