im new to this site and just wanted to say hello and ask a few questions. im new to the nano tanks but not to reef keeping. i just bought a oceanic bio cube 29 and was wondering what mods should i do to it before it is set up. i was thinking of adding another pump but was unsure where to instal it. i removed all the bio balls and will put live rock rubble in it. im not sure i need the pump right now but i dont want to have to add one later. any thoughts? thanks
