Suggestions for RO Water Storage?

[Natterjak]

I want to set up my RO/DI to automatically fill a holding container (I bought a float valve) - does anyone know of a good container to use? I have a few of the 32g Brute cans, but they're round, and I'm not sure that the bulkhead the float valve is attached to would work, as it is not a curved bulkhead. Are there any good square containers about that size that are strong enough to not bow excessively with all that water?
