Hello everyone! I am getting close to purchasing an above ground 21' 52" SWG pool that will be partially inground. It will be a self (by "self", I mean my husband) install. We are completely new to pool ownership. I'd really like to get a 2 speed pump after reading on this forum. The company I'm buying from only offers a 2hp 2 speed pump, which I think is too big. I'm still deciding between sand or cartridge filter. Would you guys care to make some suggestions, especially in pumps and filters? Thanks!
