I have a 16x48 intex pool. I have the stock pump and filter and have looked into maybe getting a sand pump but which one? West Texas we have lots of dirt blowing. I've been vacuumimg with a vacation that attaches to the suction and has a bag catcher but it takes forever..I also have the over the wall skimmer. I am looking for a good sand filter option and a good vacation option I was looking at the haward aqua bug on amazon has some good reviews?
