Hi,
I have been doing a lot of research into spray bars recently, trying to work out what will give the best flow path for small particle filtration.
Using MatLAB I modeled my fish tank and canister then I started going through the different setups.
1: Intake and output at same end, intake low, output angled at the surface.
2: Intake and output at opposite end with output angled down at the intake.
3: Intake and output at opposite end with output angled at the surface
And many other variants.
Then it struck me that the best way to get this to work is to create a corkscrew effect using the suction from the intake and an L-Shaped spray bar.
I made it nearly three the entire length of the tank on the back wall, and the whole width.
For the holes i I worked out how big they were on my Eheim spray bar, how far apart each hole was and how many in total.
The spray bar i built was 5 times as long, so I halved the hole size and tripled the distance between them..
Now for the angles of attack, the spray across the back is aimed at the surface of the water and going towards the front glass.
The spray across the end is angled down at 45°
The result, the spraybar at the back sets up a very fast spinning motion, the spraybar across the width forces the water to start moving towards the inlet as does the suction from the intake.
It is nearly impossible from my modeling and calculations for anything to stay in the water column with this configuration, and zero dead zones on the floor of the tank even with ornaments in there
My water is like glass!!!
