A lot of people put egg crate on the bottom to prevent damage from accidental falls and increased pressure. Then it's a case of spreading the load evenly so the weight is distributed across the bottom and not too concentrated at one end.
When you think about the weight of water a tank has to hold, the rock makes little difference as long as the load is well balanced and the tank is supported as per manufacturer's instructions and properly levelled.
You can reduce the weight in Rift Lake tanks by using some Ocean Rock, which is actually limestone and full of holes and is less dense than solid rocks, or Lava Rock which is also lighter than the same volume of rocks like slate.
