The only way to lower the salt concentration is to partially drain the pool and refill with fresh water.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline
together. Use the chart on page 11 to determine how much stabilizer must be added to raise the
level to 30 ppm.
