Slick vinyl pool

Usually this is a cleaning problem that concrete pools do not have. The bacteria that builds up is more aparent in vinyl pools and makes them slick. There are solutions and one is to make sure that you use the "shock" treatment for your pool. Another is to use the proper chlorine additive. The third is surprising, but effective... put some copper in the bottom of the pool. Pennies are effective and will help keep the "slime" from building up. If your pool is small enough, scrub the sides and bottom of the pool with a brush to clean the "slime" off and allow the chemicals to work.
