I have an intex 18x9x52 with a sand filter, no skimmer. Just has the hose that pulls in the water to go thru the filter and the hose that returns the clean water. Bought an Aqua Critter pool vacuum. How do i hook this thing up to the filter to get it to vacuum? newbie to this board but have been using Intex easy-set pools for four years and i understand we have to rig things up sometimes-- just want to make sure I am not missing something before i start getting creative. thanks!
