Any Clever or alternative 3x3 Flood tray Ideas?

[St. Phatty]

Home Depot sells concrete mixing tubs for about $12.

They're 2 feet by 3 feet (outside dimensions) and about 7 inches deep.

I just use them to catch run-off, but they're heavy duty enough to do a flood-drain/ ebb-flo type system.

Yeah I checked them out. The sides are heavily sloped though so not very ideal for my setup (vertical) the $17 ace tubs are perfect and are 8" deep while still maintaining a rectangle shape.
