Hey TFP. So I'm pretty new to the pool world, I bought a house in Aug, and it came with a 18×34 oval above ground pool. I've been reading and reading here all while learning a lot. The pump that I currently have seems like an older setup and is kind of loud. It stills works but I'm weighing options on getting a new setup. My local pool guy said he would advise me to switch from the cartridge filter to a sand filter... I figured I would come here and ask what you guys/gals think in should do. Should I replace what I have and if so, with what? I tried to attach pics of what I have but it says they are too large.
