Why Does a Pool Need to be Brushed?
Brushing is important. There can be dead spots in the pool circulation where a boundary layer can form adjacent to certain spots of the pool surface. While the overall Cl reading can be acceptable, these boundary layer spots can be low in Cl and algae can develop.
Algae has a biofilm that protects it. Brushing the pool surfaces breaks the algae's biofilm and allow the chlorine to attack it. That is why frequent brushing during the SLAM Process is important to its success. All pool surfaces should be brushed at least weekly during normal maintenance.
Wall Brushes
A pool owner should have at least one good brush.
A basic 18" Nylon pool brush is fine for smaller pools. This brush has a spoiler fin to hold tight to walls.
If you have a larger pool then a 24″ wall brush with nylon bristles and a reinforced metal spoiler fin may save you time and last longer.
