1kg tub of Alkalinity Plus for your hot tub, spa or swimming pool.
Compatible with other hot tub chemicals.
Add to your hot tub, spa or swimming pool to raise the alkalinity level.
Alkalinity Plus raises the alkalinity level of your pool or hot tub water without raising the ph level. Maintaining the correct pH helps prevent corrosive water, high chlorine consumption and pH fluctuation. Use directly by spreading evenly across the surface of the water.
