over flow jbj

[mannaize]

So it's been a while since I have worked on my jbj 12 G project but I am starting it back

 

But I forgot an idea I had so long ago. Since I have such a small tank I want as much room as possible. So therefore I don't want to make a overflow.

 

 

Can I run two (because I have two holes) pvc pipes from the holes to the height of water needed in the tank. So from the gravity water will run down the pipes. Then I will put a screen over the pipes so no snails or anything hours down them.

 

Why do I want to do this?

So I can stack rocks up against the pipes to hide them. Plus I can grow corals I'm the pipes. Then the fish can swim between them. It's to gain room in my small tank.

 

In a over flow the pipes rise up half the height of the overflow. Water falls down into the over flow and hours into the pipes, but water acculmates above the pipes a couple inches right?

 

So will My idea work?
