Measuring Free Chlorine in Your Pool: A Step-by-Step Guide
Measuring the free chlorine in your pool is an important part of keeping your pool clean and safe. Here’s a step-by-step guide to help you get it done.
1. Gather your supplies. You’ll need a pool test kit, a clean container, and a pool brush.
2. Brush the walls and floor of your pool to remove any dirt or debris.
3. Fill the clean container with pool water.
4. Follow the instructions on your pool test kit to measure the free chlorine in the water.
