Swimming Pool Since 2012 I have a Swimming Pool in my backyard, it's not so big (7x4mt), even so it's hard for me to keep the water clean, every day I turn on the filters for two hours, and in the night I pour the chemicals into the water. it's a lot of work but is really satisfactory when at the other day, my cousins and I, can spend all day in there, swimming, playing waterpolo and voleyball, and the water it's clear and clean. The other day I was concerned because I poured copper sulfate that I read is an Anti-algae (green thing that makes the water.. green) it suppouse to make the water clear, but instead the water started to look cloudy, like if instead of pouring that I would have poured flour, I was scared and start too search for information about that, I read that in a specific Ph (8,0) if the water contains chlorine and you pour Copper sulfate to the mix, it would transform into Copper chloride that is corrosive and bad even to breath it. Also the next day would come to visit us my little cousins, I imagine that if they swim in that water would melt or something like that. One of the solutions of the internet was to empty the pool, but that wasn't an option, 30,000 lt of water doesn't go in a night and then I have to full it. Finally nothing happens, the water was a little cloudy but not acid or something like that. For now on I just gonna use apropiated chemecals and I will not to play to be Heisenberg Hope you like the story! Waiting for corrections. Here is one of my cousins in the pool last week
