Hi,
Some one did a lovely test and published it on Youtube. The ice did just about nothing. Nor do the back flush devices work well. Sewer solution works a bit better, if there is a "straight shot" into the tank and if the water pressure is high. Rinse sprayers at the top of the tank do the best.

When we deep sea fish for tuna we make an ice slurry in the bow compartment and when it starts to melt we can hear the ice cubes sloshing back and forth rubbing against all sides of the aluminum compartment so I have to believe that 30#'s of ice does something, YRMV
