Ok, so maybe I did some guessing on some of the numbers in my signature...?
You guys did steer me towards the SuperFlo in another post, but I also saw that name pop up on several other threads and it ranked pretty well on some of those "most efficient 2 speed pumps" posts. I was also thinking about the Hayward Super Pump 2 Speed, 1 HP for the same reasons. I really have no idea what I'm looking for in a pump. I tried calling around to some local pool stores, but they will only talk to you if you want to buy what they happen to have in stock, not what's best for your situation.
I don't even know how I find out what my gpm and sqft of the cartridge is... Is it likely to be printed somewhere on the metal tube that the cartridge goes in or is it related to the actual cartridge part?
Can you tell me what I need to know about my filter system BEFORE I decide on a pump?
I appreciate all your help with this!
