Greetings all. I'm looking at adding a timer on my pump/filter this year in order to try and save some money on my light bill. I have an 18x36 IG pool. My questio is this, is there any certain brand or features you guys that have them would reccomend, and how long should I let my pump run to make sure it is filtering the water? My pool is scheduled to be opened Friday the 13th! My light bill is usually about 1/2 in the winter when my pool is closed, and it is supposed to be more then. I have been running mine 24/7 for the last 3 years. TIA.
