overflow box pvc pieces

[camineet]

Hey wondering why makers of high quality overflow boxes like modular marine and exotic marine don't include the 3 pvc sets for the inside of the external box.

Is there something about these pieces that has to be specific to each setup preventing these sellers from just including them? To be clear, I'm talking about the full siphon, the durso one, and the emergency. Like, is there some reason that we have to do that part ourselves based on our specific setups?

I see your point. Aqueon sells a mega flow kit, where all the work is done for you; kind of ‘idiot proof,’ as the saying goes. But that seems to be the exception.
