I have a severe case of algae. When I opened my pool over a month ago it looked like a swamp. I brought my chemicals up to normal then started shocking it after two weeks and no improvement I started shocking very heavy. My chlorine is off the charts high and has been that way for over two weeks and the pool still looks the same. I have vacuumed everyday. I have spent a more money on chlorine and shock over the past 6 weeks then I normally spend in a year. I have been think about giving up and draining the pool cleaning it and starting over. In the 10 years I have had this pool I have never had this problem.
