I have an approx 20,000 gal in-ground plaster pool. I converted it to a salt water pool about 10 years ago and it has been mostly trouble free with little maintenance required. I have a Pool Saver opaque pool cover, which saves tremendously on water and chemical costs! I had replaced the original Anthony pool equipment with Sta-Rite DE filter, Sta-Rite heater and Hayward variable speed pump about 11 years ago. I also have 7 12' Fafco solar panels on my roof. I have done all of my own pool maintenance for the past 35 years.
