I found a couple posts where folks have dealt with the water that collects in the "V" at the top of the Intex Ultraframe liner, but none offer a semi-permanent low maintenance solution. My pool has only been up for a couple weeks, but I can already feel the trapped water becoming "slimy" and see it becoming a breading ground for mosquitoes and algae.
I thought of drilling small (1/8" or smaller) holes, one at each leg opening, at the base of the "V" draining outward. "Theoretically" this would allow only a small amount of water to be trapped in this area and new water would constantly flush the old out. I don't dare do this before consulting with the experts, so thanks for any advice.
