I guess if you think about it...
the larger the tank the larger the margin for errors.. especially for beginners. Thats why alot of ppl go against nanos at first... little mistakes make big problems, esp. if your just starting (I know I made my fair share of mistakes
)
If you have the money/time/resources go for it! Everyone pretty much wishes they had a larger tank right? talk about setting a standard.
Thanks for posting your project as it motors along. Its nice to watch it 'grow'.
