Halves is good as you don't want to remove too much as there is also good stuff on the tank floor.
Try maintaining by less digging and I put money on the fish being more settled. Others say dig, but outbid experience this isn't the best approach unless you have a very high cleaning regime and crap on the bottom hasn't had a chance to build.
-.- stirring up waste via cleaning introduces no more ammonia than does the waste sitting there rotting.
