Need to replace liner and am being told I need to use Aquasport liner on my Aquasport 52 (15x24 oval)..my neighbor just used a unibead/j channel liner in his. ..but my pool guy is telling me it has to be Aquasport liner...my issue is the lack of design in Aquasport and another 4 week wait..otherwise i can get another liner hopefully by weeks end at Amazon...want to get liner in pool as soon as possible as I have a hole in my backyard and sunny days ahead in NY..thanks in advance
