Using clear plastic tubes from the fish shop & white tapes for pipes connection.
This over flow is inspired by other youtube video on the overflow configuration with my little modification to better suit my shrimps :3
The DIY sump uses 3 pails with many holes at the bottom to drain water through them easily with 3 layers of filter medium.
Added a Ultraviolet UV pump in the sump to kill bacterias & germs plus a 3 meter water pump with adjustable valves to control the water flow.
Drilled a hole at the return pipe to prevent back flow in case the water pump stops running and caused a back flow from main tank.
Time taken to complete: 2 days
