What's the actual cost of a 30 gallon tank against a 20? Pretty minor in the total cost. I'd rather plonk the stuff needed for a 20 on a 30, you're only paying for the glass and an extra 10 gals water. If you also only stocked for a 20 you would have a real easy time.
Please accep that I'm using a 20 and a 30 as an example. A better example is between a 10 and a 20 where the difference is much more significant.
