So a 96 by 48 by 24 would be how many gallons? How much do you think it will weigh? It would be on concrete. Be theres mesh at the bottom so if it broke that...

To know how much it will weigh we have to know what you're constructing it out of to guess. I don't get the mesh at the bottom???

But I agree make it 84x48 or if you can 96x48... for rays obviously height not as important as width/length..
