So i just spent an hour chatting with intex about getting a replacement liner for my agp. The insist the new season ultra xtr frame 18x52 liner will not fit my pool. They then say the only difference is the color, and the outlets/inlets. I already had switch my pool to different inlets/outlets so i could use pvc instead of cheap hoses. Has anyone tried to use the new intex ultra xtr liners with their existing ultra frame? Apologies if this has been answered in the past, I'm new to this forum. Thanks in advance.
