Finally made the plunge in to the Intex metal frame world recently. I'm intending to add a sand filter and SWG to the 16' x 48" before next season.
For the SWG, I think I've settled on Intex #54601, rated at 1650gph. For the filter, #56673 matches this flow pretty well at 1600 gph. For not much more money, I could get #56671 with nearly 2X the media. Is a 2650 gph pump too much for the 1650 gph SWG?
