Just started my the project making a riverbank in my 540 Liter.
You meantioned

You can get unidirectional current using a manifold of PVC pipes with sponges and power heads. I have also seen a good inidirectional flow tank using large power filters. Simply attach a PVC elbow to the intake of the power filter and run a PVC pipe to the other end of the tank

What should this "manifold" look like?

Thanks for any input

I think it would be suitable diameter 'plumbing' pipe that runs down from the powerhead, angled 45 degrees and run the whole length of the tank with an 'upright' at the end to take in water, thus creating a single flow direction as opposed to 'tumbling' the water.

ps Just checked out your site Paul and I have a male L183 and I have never been able to find a mate for him. I would dearly love to breed them but he was the only one I could get my hands on over here!! Lovely fish ( It's great what you did for the Dull Eyed Panaque).

I just had a huge sellout of L-183 youngsters, some 250+ sold at kr 60,- (4-5 pounds) a piece

Chill,

Try going to clayt101's site. Then check out the river aquarium from the main menu. It maybe the pne you are looking for or maybe the one Shane is suggesting.

I have been planning to do something similar for a while now but instead of powerheads I am considering using a converted three speed central heating pump, this way I can slow the flow down and increase again when needed.

Hi!
Yes this setup is pretty cool!
I wanted to do so as well but it is a good piece of work.
I have also read an article in the Datz and in the BSSW about such system.
The article in the Datz is about a big tank in which in the middle a piece of glass as cut the Aquarium in half but the piece does not reach each end, it sort of make the water make a circle inside the tank, and sort of look like what is going on in river as well!
The project look pretty cool!
Cheers!
Yann

In the past two issues of FAMA there's been an article about how to set up a system like this if anyone wants to read more.
