New Pump and Filter for a 21ft round.

Hi guys.
I have a Lomart pool with a Spectra 3 tank and a promega 1 hp pump w/timer, both are getting older. Long story short I would like to replace both with something new. I can replace both with new updated versions of these products or maybe go another route. Any tips on maybe switching to a cartridge filter with a new pump? Or stick with a sand filter, but a larger tank? I have a 21ft above ground. Any advise on what I should get. If anyone can recommend me a good set up , I would really appreciate it. Thanks. Also, would a 1.5 hp pump be to big?

Hi Reefdiver,

One of the equipment gurus will be by soon, I'm sure, to answer your questions....just wanted to say that a 1.5 hp motor will be way too big for this pool--if the water level is 4" deep, I estimate about 11000 gallons. I have a 1 HP pump on my roughly 26K gallon pool and it's plenty big enough...
