We just finished our new house with a small 15 x 25 x 4 ft deep lounging pool it is a "Saltwater" pool with plaster. I have a retractable cover on it ost of the day to keep vermin and KIDS out but here is the think the dirt gets on top of the cover. I vacuum mine probably 3 times a week takes about 15 mins. I have the paper filters and no DE so no issues. the chemicals that is a different deal. I need to buy Muratic acid by the 5 gal to keep the ph down. and am still figuring out the chlorine generator deal, seems to depend on the weather and sunlight. anyway the wife wanted it so she got it now I have to deal with it. lol
