Best Way To Direct Filter Output Nozzles?

[Caprichoso]

Hiya,

Let me try to explain this properly

I want the best flow of current in my tank. How should I position the water output nozzles? At the moment, I have the filter intake on one side and the water output on the other side. I have one nozzle facing the front of the aquarium and facing slightly down. The other output nozzle is pointed towards the length of the tank, facing a bit down.

Should I have one of them pointed up so that it's agitating the water surface?

Any suggestions?

Thanks in advance!

I recently found that I got the most flow from my FX5 by removing the double-output altogether, aiming the hose end (covered by the rubber connector) slightly lower than horizontal. Fortunately for me, the pipe enters the tank horizontally through a hole in the wooden bevel, so I just use the uppermost clip to secure the pipe to the "c-clamp"

After having a fiddle earlier this week and trying to make the double-output work again, I was shocked to see how much further the tiny air bubbles were swept by the current (easily across the front of my 5-footer) when I removed it!

Let me try something here. What you want to do with your filter flow is simple. The final product that you are looking for has 2 elements.
First you want good flows through your tank. You will need to judge how well you are doing yourself.
The next factor, and seldom a major consideration, is to adjust the flow patterns to optimize surface gas exchange potentials. What I have found is that almost any flow pattern that causes the flow near the surface of the tank to be disturbed will fill the second need. Since the gaseous exchange at a surface is near ideal as long as there is some surface disturbance in the tank caused by the filter, it is seldom a critical parameter.
