Biocube 14 or diy 15g nano ?
 

The Biocube look's nice,has a built in wet dry filter and lighting it's $220 new.

The cost for a bare 15G is probably $25 , a nano power head $30, Coralife 2x24w T5 HO lights $130 - probably wouldn't get these and would look for a used 4x24w T5HO's or MH lighting.

On the face of it the Biocube 14 seams like a pretty good deal .
