If you are attempting to handle your own pool chemicals you should seek the knowledge of a professional. We have years of chemical experience and through our extensive testing have found the best way to maintain your pool for life. Plaster can last up to 25 years if properly maintained and can be diminished in as little as 1 year if not. Through our research we have found that 95% of plaster problems are caused by improper balance of chemistry. We train professionals in the latest chemistry techniques and have the ability to teach anyone how to insure proper maintenance. Hiring a chemical maintenance company is costly and unnecessary if you have proper training. Saving you money is our goal.
