How to Prevent and Treat Pool Scum Lines


Keeping a pool pristine is no small task, especially when dealing with pesky scum lines. These unsightly marks can tarnish the beauty of your oasis and may indicate underlying issues. Whether you own a pool in Ocoee, FL, or manage one, understanding how to prevent and treat pool scum lines is crucial. This guide will walk you through practical steps to maintain a sparkling pool, highlighting the role of professional pool service.


What Causes Pool Scum Lines?

Oil and Lotion Buildup

One of the primary causes of pool scum lines is the accumulation of oils and lotions. Sunscreen, body lotions, and natural skin oils can form a film on the water's surface, sticking to the pool walls and creating a scum line.

Algae Growth

Algae can also contribute to scum lines. If not properly treated, algae can cling to the sides of the pool, leaving behind a green or yellowish residue.

Hard Water and Minerals

Hard water contains high levels of calcium and other minerals that can deposit on pool surfaces, forming a scum line. These mineral deposits are often more challenging to clean and require special attention.

Chemical Imbalance

An imbalance in pool chemicals can lead to the formation of scum lines. When the pH, alkalinity, or chlorine levels are off, it can create an environment where scum lines thrive.

How to Prevent Pool Scum Lines

Regular Skimming and Brushing

Skimming the pool regularly to remove debris and brushing the walls to dislodge any buildup is essential for preventing scum lines. It's a simple yet effective way to keep your pool clean.

Maintain Proper Chemical Levels

pH Balance

Maintaining the correct pH balance is crucial. Aim to keep the pH between 7.2 and 7.6. Regular testing and adjustments will ensure that the water remains balanced and free from scum lines.

Chlorine Levels

Chlorine helps keep the pool water clean and free from bacteria. Ensure the chlorine levels are within the recommended range of 1-3 ppm.

Use a Pool Enzyme Cleaner

Pool enzyme cleaners break down oils and organic matter, preventing them from forming scum lines. Adding an enzyme cleaner to your regular pool maintenance routine can make a significant difference.

Install a Scum Ball

A scum ball is a small, floating device that absorbs oils and lotions from the water's surface. It's an affordable and effective way to reduce scum lines.

Shower Before Swimming

Encouraging swimmers to shower before entering the pool can significantly reduce the amount of oil and lotion in the water. Providing a convenient outdoor shower can make this a practical solution.

How to Treat Existing Pool Scum Lines

Use a Tile and Vinyl Cleaner

For existing scum lines, a tile and vinyl cleaner specifically designed for pool use can be very effective. Apply the cleaner to the affected areas and scrub gently with a non-abrasive brush.

Baking Soda Paste

A homemade paste made from baking soda and water can also be used to treat scum lines. Apply the paste to the scum line, scrub with a soft brush, and rinse thoroughly.

Magic Eraser

A magic eraser is a handy tool for removing scum lines. Simply wet the eraser and scrub the affected areas. It's particularly effective for stubborn stains.

For persistent or extensive scum lines, hiring a professional pool service in Ocoee, FL, like Pure & Simple Pool Care, may be the best solution. Professionals have the expertise and tools to thoroughly clean and maintain your pool, ensuring it stays scum-free.
