I have a Coleman 16x48 Power Steel pool. I installed a skimmer in it a few weeks ago with tips from this site.
It does a nice job of keeping the surface clear. However I'm having an issue and I had this last year before the skimmer.
The water on the first foot or so is warm,however below that is is a lot cooler. I used a solar cover this year and it still has
the issue,I even just bought one of those Intex solar mats that the return water runs through. I just checked the floating
thermometer,it is about 86 deg. But I stick my arm in and once past that upper foot of water it is a lot cooler. The pool is in direct
Sunlight . Any ideas ?
