Fluid Simulator

Hi! I create glass (obstacle) of water (fluid)and couple of ice cube (obstacale) all in domain box and bake it. I made ice cube free falling to water and sink at the bootom of the glass. I want to ice once that hit the bottom of the glass go to the surface of the water. My method is set keyframe (couple of frames after ice hits bottom) before baking but wenn ice hit surface of the water it create splash effect and i don’t know where will be sufrace after baking. Is there any other method to do this something like set density of the ice and water and than ice will floathing? sry for my bad english:)
