I am looking to invest in a plexi glass (or something equivalent) that will go over my pool 20x40. I want to do this because the neighbors refuse to trim/cut t heir trees and it is a mess to clean the pool on a daily basis. Has anyone ever done this or know what the prices would look like or know where I can start to get a price? I am looking to be able to use the pool year round as well if this works out. Thanks in advance
