Oceanic Cube-Fan Direction ?

[427HISS]

I bought two 14g Oceanic BioCubes and fixing both. What direction do you want the two fan's in the hood to move ?

One fresh air in, the other out.

OR

Both in or both out.



Thanks,
Kevin

Factory they are one in and one out. When I owned the biocube I replaced them factory.

What did you replace them with and did you keep them one in one out ?
I know years ago, the Coralife hood with the halides, they ran one bringing in fresh air and the other blowing hot air out.
