wide mouth skimmer/sand filter upgrade

Had a 16x48 ago for a few years just upgraded to a 22x52 pool...we live on a gravel road and get extra dust...was wanting to get opinions on sand filters and wide mouth skimmers...I get a lot of insect debris on top and pool is too large to skim....any pointers would be great....looking at the Intex sand filter for $180 says it covers 12000 gallons but would like others input. Thanks!

Is this a soft side pool, like Intex? Or a metal side standard above ground?
