Here's what I do with ANYTHING I am DIYing....... Take the most extreme recomendation and make it better than that. If someone recommends 500 pot scrubbies get 700. If someone recomends a 2 by 4 use a 2 by 6. Overkill/better safe then sorry never hurt anyone. Do you want to loose sleep over wondering if you are going to wake up in the middle of the night to a loud crash that your tanks just made falling onto the cement floor? If it was ME building that stand it would have double 2 by 6s. Why? Cause A single 2 by 6 was suggested and so was doubled 2 by 4s. Double 2 by 6s leaves NO doubt it will be strong enough doesn't it?
Seriously can you put a price tag on piece of mind? If you could I bet it is worth a lot more than the price difference between a 2 by 4 and (2) 2 by sixes. Would 2 by 4s work? Maybe..... Would it kill you to walk to work? No. But you drive anyways. Get my point?
