For a sequence $\\{a_{n}\\}$, its sum of the first $n$ terms is $S_{n}$. If $a_{n} > 0$ and $a_{n}=2 \sqrt {S_{n}}-1$,  
(Ⅰ) find the general term formula for the sequence $\\{a_{n}\\}$;  
(Ⅱ) let $b_{n}= \frac {a_{n}}{3^{n}}$, find the sum of the first $n$ terms of the sequence $\\{b_{n}\\}$, denoted by $T_{n}$.
