Green algae in pools

Living in Andalucia has its own difficulties with regards to swimming pools. The intense heat and hard water add up to problem after problem. After paying out a small fortune on your swimming pool build, you now have to maintain it. Green algae ridden water is a major problem. In most cases a dose of shock chlorine will get rid of it. This product can be granular or liquid.  The best way I have found to add the shock, is to add the chlorine shock in the evening with the pool turned off. In the morning, you should be able to see through the water again and start to clean up. Never swim whilst there is green algae in the pool. Apart from it looking ugly, it harbours a multitude of yukki bacteria and viruses such as e coli. I have been in business here for nine years advising people and providing them with answers and chemicals. There are so many things that can go wrong with pools, that it would take a lifetime to know all the answers.  I dont know all the answers, but with your input, I think we can solve a lot of problems together.
