att: fishman, re internal tank plumbing (was spend now save later)

we were saying...



hi fishman, I did the same thing, but I just used a piece of piping. I
don't know why so many people go to the trouble of sectioning off a
corner..
it gets dirty is hard to clean, and it doesn't look any nicer than a
discreetly placed piece of black pvc pipe.


How is this arranged?
A 90 deg elbow at the overflow hole and pipe downwards?

not an elbow but a T-piece. if you have an airtight pipe from the bottom of
the tank to the sump, you create a syphon, which in the event of a pump
failure will drain *all* the water from your tank, right down to the
substrate. if you use a t piece, you have one end connected to the pipe that
goes to the bottom of the tank, and one end that sticks up above the water
line in the air. The third bit of the T-piece obviously goes out the side of
the tank down to the sump. it's a neat setup. Everyone suggested to me to
do the triangle of glass in the corner of the tank method, but the way I
have I am convinced is far superior.

Yep, sounds good.
I was aware that without the "T" part you'd risk a syphon action.

It may be an advantage to section off a corner if you house large fish as
these may dislodge the pipe.
