All -
Thanks to this forum I'm making killer progress on my pool. Can actually see the bottom of the shallow end... amazing.
Now I have other questions, but the first is this: Why do I have two holes in the bottom of my skimmer? One of the holes has a plastic plate on a screw with a slot that allows it to slide back and forth, covering one of the holes completely. I also have two mystery ports in the pool, one near the skimmer, and another on the opposite side but they don't seem to do anything. Not returns or drains - wasn't sure if they were related to this.
I found another forum which I think explains the second hole, but I can't figure out exactly what the guy is talking about: http://www.poolforum.com/pf2/archive/index.php/t-9396.html
Thanks in advance for the time and help.
