I've put up my Intex Ultraframe 12'x24' above ground pool and everything works great (in large part due to the kind people on this forum). We are filling the backyard with chipped pea gravel which we'd love to come as close to the pool as possible (the pool is in a wood frame that's holding sand I leveled the ground with). I was thinking I'll get this foam tubing that's used for insulating wires (think black pool noodles) and run it around the pool so the pebbles to touch the pool... but that's getting pretty pricy. Is there a cheaper alternative people use that still looks good?
