I added one of these things to my pool and it works very well.
I run it most of the time to keep anything from sinking to the bottom. My problem is how much junk is making it down to the cartridge filter. Ants, leaf parts, etc. Just generally stuff that wouldn't make it to this filter if I hadn't added the skimmer. Wish it had a finer grate in the skimmer basket to catch smaller particles. You see any problem with adding pantyhose to the bottom of the basket to prevent this? Or maybe even something better that I haven't thought of yet?
Also, am I missing an obvious way to change my filter? With this skimmer hooked up, I'm assuming I unscrew hose at the wall, put in the plug, and then remove filter? I suppose lifting the pump above water level or adding a valve somewhere would also be options.
