Ok, here is my issue and I am hoping someone can help me out. Just bought a house that came with an above ground pool. Its a 24" wide pool. Not sure on the depth yet because it has had a big tarp nailed over it. We tore the tarp off yesterday and the liner seems to be ok. It looks fine and it holding water. There is pretty much about a 3 foot deep frog infested swamp in it right now. We have bought an Intex crystal clear sand pump filter and an Intex clearwater saltwater system for it. The research I did seemed to show that they would work with our pool. I am still curious to whether or not that is true as well. But I want to know if I should drain the pool and start from scratch or would it be cost effective to just try to "shock" the water that in it? I really have no clue. I would be super appreciative if someone could just kinda give me a good tutorial on what I should do to get this thing to where we could actually swim in it. So I am going to open this up for the pool gurus and hopefully someone can give us some advice. Thank you so much in advance.
