5 Things to Know About Swimming After Algaecide

Most algaecides are safe after 15–30 minutes With the pump running, the chemicals disperse quickly and the concentration is low enough to avoid skin or eye irritation.

Copper-based algaecides can stain swimsuits Waiting a bit longer than the minimum helps prevent discoloration of light-colored or white swimwear.

Follow “do not swim until clear” warnings If the label says to wait until the water is clear, obey that. Otherwise, you can jump in after the recommended time.
