    Pump too big???

    I've been looking what everyone here has and seems my pump may be too large. It's a waterway cartridge filter with a 1.5hp Malibu 2-speed pump. Should I have a 1hp? Did the store size it wrong? Should I exchange as I haven't used yet or maybe only run on low?

    Well definitely run on low. Not a huge difference between the 1 and 1.5 hp pump of the same model pump.

    Thanks for the suggestion. Just want to make sure everything is good before it's too late

    If it's any reassurance, take a look at my sig "My Pool" pics. I have a relatively modest Hayward C1200 single cartridge filter for my 18K pool. I also have a 2 speed/ 2HP Waterway pump. I keep it on low all the time mainly because that does well to skim the surface of my pool. I switch to high only for quick chemical mixing, vacuuming, or when we have guests. My system is doing fine.
