Hey guys. I just got a 29 gallon biocube used. I do not have the sponge filter, refugium strainer, overflow tray or filter cartridge as seen here: http://www.oceanicsystems.com/assets/008/27055.pdf
I have everything else and i also have a bag of purigen and SeaGel. Can i just throw these bags in the back without all that equipment and call it good or do i need those pieces of equipment? Will the live rock and sand act as natural filters ? I am really worried as i just bought all my live rock and salt water and i need to get it in the tank.
