Alkalinity too low

Low alkalinity often results from heavy rainfall, acid shock treatment, overdosing on pH reducer, or simply very soft fill water. When alkalinity is low, the pH becomes unstable and fluctuates constantly, making the water difficult to balance.

To increase alkalinity, use a productAlkalinity PlusTo reduce it, we usepH Lessbecause it directly affects total alkalinity. Always follow the manufacturer's instructions to avoid sudden changes.

To lower the alkalinity, add pH Minus in small doses, always in the same spot (ideally in the current towards the bottom). Then let the pump circulate the water. When the pH drops too low, raise it with pH Plus. Repeat this process until the pH returns to between 80 and 120 ppm.

To increase alkalinity, use an Alkalinity Plus product. Pour it around the pool with the pump running. Retest after 1 hour. The goal is to reach between80 and 120 ppmfor swimming pools.
