Sand filter fouls pretty much any time I do a manual vac

Is it pretty typical for a sand filter to foul up when manual vacuuming through the filter? Granted - being an Intex sand filter and likely undersized a bit doesn't help, but seems like there's no way I can vacuum the entire bottom of my pool (and it's not that big!) without having to backwash. And the bottom is not even that dirty.

I'm gaging this mostly by the reduced suction and reduced return flow - not necessarily a 25% rise in filter pressure. But it's noticeable.

Amazon has a great deal on the Intex suction-side auto cleaner right now, but I'm a bit hesitant to get any suction side cleaner if it pretty much will foul up the filter quickly. Without vacuuming, the pump/filter go weeks if not months without needing a backwash.
 
You're right, a 12" filter is really small. Not much capacity for anything. You'd probably be better-off investing in a 18 - 21" filter and separate pump not only for vacuuming more efficiently, but also for better water circulation and the potential to add an addition return jet and/or fountain if you wanted. Those smaller combos really don't give you much to work with.

Thanks for the response @TexasSplash. The lack of circulation is one reason I was thinking about running a suction side cleaner daily or every other day. I don't mind vacuuming necessarily, but with this above ground pool - seems like if it sits for a week even with plenty of Chlorine in the bulk of the water - algae starts taking over on the surfaces!

Rats! Well, that means it's SLAM time. SLAM Process
