no idea.
the 2nd fuge is just for the hell of it, i had the room, had the equipment, figured it would come in handy for all sorts of things. idea now is to kick start pod growth then i'll chuck the ones that grow in there into the main fuge and hopefully it should multiple from there. idea later could use it as a qt tank, might breed clowns in it, might have it as a trial nano or even a separate frag grow out tank. who knows?
