No matter what type of stain you have, the first step is to test your water and check your balance. If your water is not balanced, removing the stain will be more difficult.
For Organic Stains: Once your water is balanced, super shock your pool with calcium hypochlorite. Once the shock has circulated for a few hours, apply granular chlorine to the stain and scrub it away.
For Metal/Mineral Stains: Use a stain remover designed to remove stains caused by that specific metal or mineral. Follow the instructions on the label carefully.
For Scale Stains: There are a few ways to remove scale. The easiest method is to purchase a calcium stain remover and add it to the water, or apply it directly to the stain. You can use a stain eraser or a pumice stone to scrub the area for scale on tile.
Most stain removers do not require you to drain your pool. However, if your staining is more severe or your first course of treatment has not removed the stain, you may need to drain your pool to gain easier access to the stain. Here are some additional tips for removing stains from your pool:
