Brushing your above ground pool walls

This is a major part of pool circulation. Every pool is going to have a few dead spots, so practicing good circulation also includes brushing your pool. You should brush your pool often, at least once a week.

Brushing dead areas and other areas of your pool helps to break up debris or micro-organisms, like algae. It gets these inhabits into the water, instead of clinging to other parts of your pool, so that your filter will have an opportunity to filter them out. Around the ladder, in an above ground pool, is a good  spot to start.
