Does anyone know how much electricity an Intex 1000 GPH pump filter uses? I have a 15 foot pool and am running it the recommended 4 hours a day. From what I've heard these pump are quite weak and don't help that much. Wondering if I should run it more or less. My inflatable pool is less than 3,000 gallons so I wouldn't want to waste water, but it wouldn't be that big of a deal if I had to drain and refill it by the end of the season. Also, are there certain times of the day or cycles when it's more effective to run it?
