I'm putting up my 18'x48" Intex Ultra Frame pool this weekend. I also have the larger 2650gph Intex Sand filter. What vacuum can I get to use with this and how do I connect it? Eventually I'd like to put the in wall skimmer in (I hate that it doesn't have this like the regular Intex pools do). I'm assuming that I will have wrinkles on the bottom of the pool, so I'm not sure I'm looking to buy one of the automatic vacuums, so I'm just looking for a good, relatively inexpensive manual vacuum that will connect to the filter I have. Thanks.
