Hello, I recently purchased an 18 foot round metal frame intex pool with a vinyl liner. I have started filling it with water and am following the super simple chemistry plan posted under the chemistry care for Intex pools. So far so good. I am curious as to what the best vacuum would be for this pool? I have seen battery operated ones and pump operated ones, and I'm just totally in the dark as to what would be best. Also, I keep reading about skimmers and chlorine tablets. I was going to purchase the Kemtek dichlor from Amazon, but I am not sure if i should use tablets that go in a skimmer or powder I add myself. I don't mind doing it myself, just wondering what is best.
