Hi Annamarie, We offer free water testing here at Namco. If you bring a sample of your pool water into our Swansea location, we would be happy to tell you about your pool's chemical levels and how to rectify your issue.
It sounds like algicide is needed. If u have a pool place that sells chlorine and other pool chemicals. There a place in Smithfield called Creative pools ,they can help u. Bring a sample of pool water to this place or other pool places. Good luck.
