Propane Bottle Question

With crawfish season more or less here, i had a question about my propane bottle. I have the standard blue rhino bottle that you can buy just about anywhere. But i also have a 30 psi regulator on my burner instead of the 10 psi that a lot have. Am i fully utilizing the capability of my 185,000 btu burner and 30 psi regulator with one of these bottles?



If i'm not, what can i do??? I know northern tool sells the bigger bottles but am not sure what difference that would make??



Curious, thanks for any input.
