We finally have a sparkling pool after a long battle with algae. The water is crystal clear and we were finally enjoying our pool! We came home yesterday from work to find "soapy looking" bubbles all over the pool. We have some air in our lines and need to have some pipes replaced (next year) so the jets do produce some air bubbles, but they have never turned into sudsy bubbles before. What is causing this? Has anyone seen this before??
