      It can prevent scale(Pools water absorb particles from the outside air, then settle to the bottom, finally build up as layers of scale film)/ prevent stains(Pool stains are often a mixture of spores, bacteria, dirt, minerals, oils or from tiny metal objects in the pool)/ prevent algae(Algae can find a ready source of dusty food and establish a firm foothold in dirty pool water) and prevent etching.

   When to brush a pool?
      My advise is that brush your pool weekly. If you are too busy to arrange a good regular brushing to avoid expensive damages, be sure to make time for pool brushing when you see stain/algae in your pool(they cannot be removed by mere pool chemicals alone, there must be some physical persuasion), or after adding chemicals(to dissolve and disperse the chemicals so they won’t etch, stain or scale the surface).
