Don't go by a pool with an Intex pump. As I mentioned before they are rather pathetic. The Dynamo would have solved all those issues. But exactly how did you know for a fact that you weren't getting full circulation? Did you take multiple FC readings around the perimeter of the pool and did you see a large variation? That would be surprising to me.

As for multiple skimmers. Having two skimmers splits the flow so skimming action is reduced in each skimmer by 50%. Combined with low speed, it can be almost non-existent. I would only recommend a second skimmer for a very large pool or one with a potential dead spot (e.g. L shaped). AG pools don't tend to have dead spots. Also, if you have prevailing winds for the most part in a single direction, all debris will tend to flow toward one end of the pool and that is where the skimmer should be located. In this case, a second skimmer won't do you much good and you are better off with a single skimmer.
