The best way to keep your swimming pool free from algae and bacteria and looking and feeling crystal clear is to shock it once a week with Blast. This chlorine free pool shock revitalizes the existing chlorine and allows you to swim right away, instead of having to wait long periods of time as with gallon jugs of liquid chlorine. This year, make pool maintenance easy and experience clean water all summer long. Make sure to keep your alkalinity and pH in line and keep your chlorine residual at the recommended level. Feel free to give us a call with any pool supply questions or watch any of our pool school videos online.
