Problem of the Month: Water Scum Line


What is it?

A coating on the wall of the pool along the waterline which feels greasy.  Most of the time it is due to oils, lotions and other organic contaminants that enter the water via swimmers, causing a greasy build-up.  By not attending to this problem, you may see some staining along the water line of the vinyl liner.


Brushing the pool wall is often overlooked by pool owners as the process can be time consuming.  But to prevent a water scum line or possible staining it should be a part of your regular maintenance routine.  The best prevention to avoid this issue is to brush your pool walls at least once a week and use a product, such as BioGuard’s Pool Complete or Natural Result, with your weekly maintenance.  An automatic pool cleaner can also help with the scum line if you invest in one that will clean up to the water line of the pool. 

Problem Solver:

Use a brush and Off the Wall® to quickly clean surfaces near the waterline.

Add Pool Tonic to remove contaminants such as oils, lotions, and grease.

Using Pool Complete or Natural Result on a weekly basis will aid in removing the contaminants weekly so you may not require brushing as often.
