If you are bottle carbonating you need the yeast to produce CO2, at the same time more sediment will be created in the bottle during carbonation... You can reduce the amount in the bottles a couple of ways, add gelatin 3 days before bottling, let your bottling bucket rest to settle out the sediment. My preference is to rack to a secondary for clearing about a week before bottling which removes enough for my taste and gives me a clear beer that has a better taste. Beyond that I have learned how to pour carefully which is the real secret to clean and clear brew...
