Yay! finally got my water all cleared and my unicel filters are in. REALLY! am I the only one that can't get them to work in the intex pump. I ordered the ones for the type B and when you compare them to the cheap Walmart filters they should be the same size but. the whole is the exact same size as the little part where it should sit on top and bottom. Tried using Vaseline even to get it together with no luck. Anyone else have this issue? What am I doing wrong?
