I am looking to purchase an above ground pool. I am a single mom, 4 kids 8 down to 4. I have 1/2 an acre. I am looking at either a 27ft or 30ft pool. Not sure which one. Also not sure of all resin by Blue Cascade or Harmony, or a hybrid. Also salt vs chlorine, and a variable speed Hayward pump. What about a plastic layer before the pool liner to protect from insect eating the liner. Any thoughts are greatly appreciated. I was priced at 10k for everything including install for a 30ft all resin Harmony. With a variable speed pump, robotic cleaner, plastic before the liner. Is this crazy high. The owner would do the install. That is also open and close and all the chemicals for 12 weeks.
