A pool might be a luxury, but still it needs regular cleaning to keep it clean and stain-free. By shocking your pool with a chlorine solution, you can get away with a lot of the organic stains. Apply a strong dosage of chlorine on the stain and scrub it away with a brush. If the organic stain is along a waterline, an enzyme cleaning might assist. Organic stains of many forms might end up in your pool.

Brown and green ones are biological and come from leaves or natural debris, and they often resemble algae. These are all the simplest stains to get rid of. A few of the tougher stains have a black or reddish hue and are frequently metallic in nature, originating from copper, iron, or manganese. These metals may be mixed with water, especially if the pH levels are really not stored correctly or if you reside in a hard water location.

A first step in removing organic water stains is to shock the pool using chlorine. Put a strong dosage of chlorine just on stain and wipe this with a brush. For most cases, this procedure will remove the discoloration completely. If the stain is near the waterline, an enzyme-based compound can be used. These cleansers operate by erasing the oils that bind debris at the waterline and removing any stains with little or no scouring. 

To remove any remaining pool stains, use a tile or vinyl cleaner designed exclusively for swimming pools. You could use ascorbic acid or diphosphonic acid-based cleansers for spots that require lots of scrubbing. These are more helpful on stains that are difficult to remove. This method works best in the winter, once the pool is emptied and you have access to the full region. Ensure that swimming pool is protected during wintertime to stop material from entering the swimming pool and generating organic pool stains.
