I'm looking to buy a filter for a 5000 gal. above ground pool.
The pool came with the house we bought, and the pool, filter, and pump are all a little over 10 years old. The pool and pump seem to be in good shape. but the previous owner decided to try and repair a drain plug leak on the filter by gluing the drain cap onto the tank. That has been developing increasing leaks in the two years I've owned the pool, and finally just blew off the filter when backwashing, and the threads are destroyed. Also, the filter needs a new multiport valve, as it's in bad shape too.
I'm debating just replacing the tank and cap on the current filter, but that's almost a new filter at that point, so I was thinking of getting a newer filter instead.
The old filter was a Doughboy Media Master 1300 sand filter. I'm thinking of getting a cartridge filter since I've heard they're less trouble than sand (no backwashing!) and they filter the water better than sand.
Are there any recommendations on filters for a ~5000 gal. above ground pool? I'm a complete novice when it comes to where to buy a filter, what brands are good, etc.
Any help is appreciated!
