There are floaters that you can buy, usually they're for the pucks (trichlor, I think it's the same thing as the stingy sticks), but you can look and see if the sticks will physically fit in them. If you use a floater, though, make sure that any kids in the pool don't play with it, because there can be low pH/high chlorine pockets around it that can be painful and/or damaging to the eyes. I also would recommend that you tether it from either side of the pool when the pool isn't in use, so it won't float over by your liner and fade it.
Most of us on the forum just use plain unscented bleach for chlorination, and we pour it into the skimmer or into the return stream. The problem with the trichlor is that it drives pH down and CYA up. A little CYA is necessary, but a lot of people don't realize that as your CYA level increases, so must your baseline chlorine level. By using bleach, you don't have the CYA buildup that you have with the trichlor sticks/pucks.
You can use the link to the "best guess table" in my sig to see what I mean about corresponding CYA to chlorine levels.
