This is the time of year your pool is at its busiest. All those extra swimmers leave behind contaminants in your pool and the extremely warm weather encourages the growth of bacteria and algae. Even if you’re paying attention to cleaning and chemicals these elements can sometimes combine to create pool water that looks cloudy or has a greenish tint. Instead of taking a hit and miss approach, start by getting good information. Take a sample of your pool water to a qualified pool professional for detailed analysis. Many pool stores offer this service to their customers. Armed with a water analysis and the right information they can recommend specific chemicals to correct the problem and hand you personalized instructions to get you on your way back to cleaner water.
