I'm setting up my tank with a herbie overflow. I see some setups with a u-shaped pipe on both the main drain and emergency drain. What are the purposes of these pipes?
I've been using this as my guide:
http://gmacreef.com/herbie-overflow-reef-tank-plumbing-method-basics/
It does not use u-shaped pipes.
Are the u-shaped pipes better? Quite? Etc? I was going to set my overflow up without them with the emergency drain being about 6 inch's taller than the main drain.
Thanks for any responses.
