I need help Learning How to make a 10g Sump for a Biocube. I do not know how to get the water down into the sump and back up or where I would even put a hole for the water to drain into. The tank itself has its own overflow into chamber one then goes into Wet/dry part then goes into the third chamber where it is returned back into the tank from a pump. I have the 10g tank I just don't know what else I need or how to make the compartments if you have done this please help me I don't want to mess things up but I would like to better my filtration and learn how to plumb a little tank for a future 100g tank.
