Hot Tub Water Balancing
Hot tub water heats, aerates and turns over far faster than a pool, so pH and alkalinity drift quickly and need correcting more often. These adjusters are measured for spa volumes, so a small dose does the job without overshooting – pH up and down, alkalinity increaser and calcium hardness for soft water areas.
