How Long After Adding Algaecide Can You Swim Safely?
You can usually swim safely 24 to 48 hours after adding algaecide to your pool, depending on the type and ingredients used. Copper-based algaecides often require about 24 hours, while others like quaternary ammonium compounds may need up to 48 hours to avoid skin irritation.
Warm water, sunlight, and good filtration can speed up this process. Following label instructions and ensuring your pool’s clear and balanced will help. Keep checking for tips to make your pool safe faster.
