You should brush your pool at least once a week in normal conditions. If the pool experiences heavier usage or a heavy storm, you may need to brush more frequently.

There are many factors that you need to consider when choosing the best brush for your pool:

• Pool Shape: If your pool has curved walls or corners, a brush with an angled or curved head may be more effective in reaching those hard-to-reach areas.
• Bristle Type: Softer bristles, such as nylon, are suitable for vinyl-lined pools as they are more gentle on the more delicate surfaces.
• Brush Width: Choose a width that allows you to cover a good area without missing too many spots. If you choose a wide brush, you may struggle to get around obstacles, but if it's too narrow, the brushing will take too long.
• Handle/Connection: Ensure that the brush head fits your telescopic pole.

The lifespan of your pool brush depends on how frequently you use it, the surface material it’s used on, how well you care for your brush, and exposure to the sun / harsh chemicals in your pool. Replace your brush when you notice the bristles are worn out or bent, the head is cracked, you’re losing bristles, or it no longer brushes effectively.

While brushing does help combat algae, persistent algae or discoloration may indicate a circulation or filtration issue, a chemical imbalance, or low-sun areas that promote algae growth in your pool. You may need to adjust your sanitizer levels, shock your pool, clean or backwash the filter, and inspect your circulation jets.
