For all pool owners, having algae on the surface of your water is a clear sign that your pool may not be sanitary.  Filters play a role in keeping your pool clean but it also needs some help to maintain that crystal clear blue water that every person desires.  Sometimes chemicals are necessary to improve the condition of your water.  Pool and spa products were created for people who desire simple to use products that take the guess work out of maintaining their pool and spa. Companies are now developing sensible solutions that focus both on the environment and the best interests of commerce and the consumer.  Anything from algaecides, pool shocks, and chemical-free products, pool chemicals play a vital role in maintaining a pleasurable swim.
