Long story short, the tenets living in my house neglected the pool. It's since been uncovered for two years, and has a bunch of **** in it. Last summer there was frogs living in it too. I'm sure there's probably a few neighborhood cats in there as well. It looks like a lagoon. I really want to clean this but I CANNOT spend that much money on it. I DO know that I definitely need to purchase chlorine though. I'm brand new at this, never worked on a pool before. It looks like everything else for the pool (chemicals, vaccuum, etc are all here. There's a big filter on the side of the house. I don't want to turn it on untill I know what I'm doing. I can take pictures if needed. By the way, this is an in-ground pool. APPOX 40 feet long by 15 wide.
