I am new to Aquaponics and started experimenting with different types of siphon in a tiny Aquaponics system see my video https://www.youtube.com/watch?v=6MZC...ature=youtu.be


My fish tank is 2 feet by 5 inch by 9 inch (H)

My inflow pipe is 8mm diameter and fills up my GB in 1 minute.

With a bell siphon with stand pipe of 12mm, it can drain my GB in 45 seconds.
It first takes a few false start to kick off. After changing to a 10mm stand pipe it started after one false start and stop right away. It now takes 1 minute to drain my GB.


With a U or loop siphon with outlow pipe of 12mm, it can drain my GB in 2 minute
It starts very easily(no false start) but takes 12 false stops to stop, and sometimes takes forever.

Hence I concluded the bell siphon is more efficient in my system.
