While the pool is down for the winter, I've decided to move away from my current cartridge filter for various reasons. I think I've decided I want to use a sand filter with a little DE added to it. The problem is that I've read conflicting information on the size of sand filter that is needed. I've read that two turnovers in 8 hours is sufficient for a filter. Then I've read that about 3.0 feet of filtering area is recommended for a small IG pool.
Here are my current pool specs:
Astral Pools USA pump - IGP2010 1HP:

I have a replacement pump (Pentair 3/4 HP) as a backup since I thought my old pump died about a year ago but I got it fixed before the replacement one arrived.

A pool calculator says I have about 8600 gallons of water in my pool, which is pretty small for an IG pool.
I'm looking at three sand filters due to cost/benefit ratio:
1) Hayward 18" S180T (can purchase for about $190 shipped)
2) hayward 21" S210T (can purchase for about $240 shipped)
2) Hayward 24" S244T (can purchase for about $305 shipped)

I know bigger is better for a filter but we don't have a ton of money to spend at this time. If I have to backwash every month that is OK but I don't want to backwash every week.
