You could always just try the 5 gallon first and if it doesn't work out just find a bigger container and switch it out.

I used to have 2 of em that I got just by asking around. One was probably 20 inches diameter and 30 in. tall with a lid. The other was 30 in diameter and 18" tall.

I think the smaller one held some type of liquid and the other held some type of pellets or something.

Good luck and take pics 8) You might also consider one of those bubblers with the little blue stones. I think they help ALOT. Reel is the baittank man. I'm sure he can give some GOOD advice.
