The tank is the 12 gallon JBJ Nano-Cube. The breeder box I was planning on useing if I had to guess is somewhere between a 24 and 32 oz. How much current needs to go through it?

Breeder box- $7.00/ but has been sitting around unused forever
Rio PowerHead- found online for $10, Havent really looked around at an LFS yet

The CPR version I found online was about $30 and was 7 3/4 in L x 4 in w x 7 1/2 in H. The breeder box is about half that size. This breeder box would fit real good without getting in the way. The CPR would probably be too big. It would fit but be in the way a little more then I would like.


Thanks,
Mike
