I didn't mean to imply you did, just creating a visual. My GFO doesn't float at all, but I use like 1/4 - 1/2 inch of low cap. The first time I used it I put half of the recommended amount, which was like 1 1/2 - 2" and it severely ticked off pretty much everything in my tank. Took me forever to get them happy again. I just keep it at a mild tumble where only the surface layer bounces around.
