if your still planning on using the skimmer, you could just place fishing line (tightened) across the top of the pool to create a partition that would keep your floating plants where they need to be. Or take some poly tubing from home depot and use a union to join the two ends of a section and then you have a floating plant ring. This would work for keeping them together as well. Just an idea.
