Bali pools often suffer from too much rain in the wet season and they can tend to turn green from garden run-off. No one wants to see their pool spoiled by algae growth, even though in itself it is not dangerous to health. The danger lies in it becoming a host to other bacteria such as e.coli. Getting treatment done promptly is the best way to remove algae, but sometimes you don’t even know it’s there until it has become a really bad infestation. Using automatic pool cleaners is helpful in keeping your pool algae free.
