Using Saltwater Pool Water on Plants: Safety Guidelines

Is It Safe for Your Garden?

Many saltwater pool owners report no harm using pool water on plants. Salt concentration in pools (2,500–4,000 ppm) is far lower than seawater (~35,000 ppm) and near human taste threshold (3,500 ppm). Still, use caution: don't concentrate discharge on a few plants.

Best Practices

If splash-out is constant in one area, plant salt-tolerant species like yucca, yaupon holly, wax myrtle, mondo grass, spiraea, viburnum, candytuft, and gaillardia. Distribute water broadly to avoid salt buildup.
