I am a new pool owner. I spoke to someone about the pool being green and not being used for 5 years, we just bought the house this past winter, and they said that they used baking soda in there pool after many attempts with algeacide, and it cleared the pool up overnight. I was wondering if anyone else has tried that and if it really worked. Would prefer not to put algaecide in the pool if I do not have to.
