Quite beautiful, you will do well

I looked at it and thought 10' x 5' so each inch of water in that tank weighs 250 lbs, hope he's cross bracing below it...

Then I misunderstood what I was looking at, thought you only had the water table under half the bed, smacked my forehead and said, "That is freakin' brilliant. Why didn't I think of that?" Then I realised you hadn't

In the real world I spend most of my time making relatively small things, I decided on an 8' x 4' table simply so I could pop a standard sheet on it.

Making small things means that by flipping the sheet I could do most of my cutting in one corner and that is where I need the water. No point in having water where I don't need it. Should I ever need the full bed length I simply accept that occasionally I will get dust.

Once I decided one corner was enough and I'd only stray out of it when I cut a long part, the slats outside my corner can suddenly have a much wider spacing because the part is long enough to span larger gaps or it would not be there.
