do you mean a rack or just how i set up tubs? You can take a look at my build at the last pages and sort of see my tubs setup. I only have a water bowl, kraft paper, and moss in the tubs now. Before i had a rack I added a plastic bowl that I cut a hole into with a soldering iron. These are 15qt tubs. I have started babies as small as 55g in these and i currently have a couple at 400g in them with plenty of room.

Basic but all my babies eat ferociously and are growing well and it didn't cost me a ton of money. I think everything without counting the thermostat cost me $25. And that includes a roll of craft paper (625ft $14).
