Jet Streams & Powerheads

[ardandy]

I'm awaiting a powerhead to increase flow in my planted (new) tank and was wondering where I should point the stream to go?

Do fish have difficulty swimming along the 'stream path' of this type of thing?

Here's a pic of my tank, you can see the nozzle from the filter on the top right, pointing towards the bottom left front of the tank.
Where would you recommend me to put the powerhead? I was thinking of putting it opposite in the top left corner pointing diagnally towards the bottom front right of the tank. Any reason why not to?

Thanks!

Depends on the type of fish you have, rippling the sufrce will create the greates oxygenation although you fish may not require this.

There is no fish at present, it was more for the plants TBH!

In that case i would go for gaseous exchange, i.e. surface agitation althou wait for UKAPS to come along and help

place it near the top pointing slghtly toward the surface and you can adjust the amount of agitation with the angle

For the plants you're not trying for surface agitation, you're aiming to eliminate any dead spots particularly at the substrate level - keeping the water well circulated and avoiding excess mulm and other detritus settling on the substrate.

I agree with this. For tanks with both fish and plants this is one of the primary compromise problems: surface agitation increases O2 for fish but decreases CO2 for plants.. and then there is the whole secondary thing of water movement at the substrate as Craster mentions.
