Flow & hole placement feedback.

[Delphinus]

I totally understand the desire to minimize the obtrusiveness of equipment in the main display.

However having said that.. with the exception of outputs/inlets in the bottom pane, which are easy enough to aquascape around and hide ... as far as the side walls go, don't you still have a bulkhead on the glass and a piece of pipe and/or nozzle? Or worse yet, in the case of using penductors - a bulkhead, pipe of pipe and a thing that looks reminiscent of an air raid siren of old? At that point you're still hiding "something" behind a pillar or something - in this case though it's permanently there and not something you can decide to move later on.

I can see that the ones on a bottom pane would not be subject to the same criteria though. But man oh man, holes on a bottom pane scare me worse. Maybe it's less of a concern with an acrylic tank but even still what happens if 2 years from now it develops a small leak? (Or does that effectively never happen unless they were installed wrong to begin with?)
