Hi everyone! I currently have a 23g as my main tank and a nano 2.6g quarantine which I'd like to convert into a mini sump. The 2.6g is sub-divided into 3 sections at the back. My idea is to put some sort of pump in the 23g to feed the 2.6g sump which would sit 0.5 meters below my 23g. In the rightmost back compartment of the 2.6g would house the inflow. Middle and leftmost section of the back will house the sponge. The main section of the 2.6g will house the bio media and outflow pump. Will this work? Any ideas would be appreciated. I can also consider taking apart all the tank dividers and install new ones in place. I just need a guide on what to do and which pumps to get. Oh, and hose size as well. No idea how to calculate those.
