We just bought a house going into foreclosure that the people completely let it go. All of it. Including the pool. I decided to start draining the pool because it was so black in there that it looked like it was on a bayou. I wasn't sure if there were snakes, gators, whatever (the pool cage is missing screens). There were none of those, but probably 100 tadpoles that I have seen in the water. However I believe the biggest problem (I could be wrong) is the algae stains covering the pool. They look like this....
I am trying to do this on a super tight budget, as the entire house needs remodeling, much more than initially intended. I do have a friends pressure washer here because the pool cage looks like it was part of the Jumanji set, so if that is an option I can do that too.
Keep in mind. I am a total newbie when it comes to pools, so if you are using terminology that regular pool users use, I won't get it (yet!) but I will gladly look it up so you don't have to dumb down your comments for me!
