I'm new to the forum and am hoping someone can asssit. We just put the Intex 18x9x52 rectangular pool (it's filling now) and I'm hoping for ideas of what to put around the bottom to make it look nicer. We're thinking rocks or mulch, but leaning towards mulch for the cost savings. Does anyone have pictures they could share? I see many online showing the round pools, but not much for the rectangular. Thanks in advance for your help.
