Increasing water flow without disturbing plants?

I have been trying to increase flow in my 20 gal to disperse the CO2 across the tank. My problem is that even my puny HOB Aqueon filter almost causes too much disturbance of the plants(they are pushed down by the flow and start to grow in a unnatural and unpleasant way.) I would like to add a small powerhead (around 75 gph or less)just to get more circulation, but I cannot seem to find a place to put it or aim it that won't push all the plants to one side.

Is there any technique to setting up the flow in the tank so it is not disturbing the plants? I know most of you guys use canister filters, but even on my 90 gal with a canister I experience this problem.

Thanks,

Hey thanks guys! That ario is interesting, At work we have one hooked into a volcano with a red LED(so the bubbles rising look like lava) its pretty cool if you are into that sort of thing. I will have to mess around with it and see if purchasing one will be in my future.

I think I might be replacing my HOB filter with a small canister. Any ideas on a decent canister for a 20 to 50 gal? (I'm also considering replacing my 20g H with a 50H - its kind of like a 75 gal but only 36" long)

Thanks guys! Barr report is always helpful.

I solved my flow problem (until the purchase of a canister). This could definitely be a great technique to those who are trying to improve flow if the canister isn't powerful enough.

I lowered my 75gph powerhead all the way to the bottom of the tank and pointed it towards the thick bush of plants that it was closest to. The base of the plants are so strongly rooted that they are not disturbed by the flow, and they make the pinpoint flow out of the powerhead into a very wide flow that is carried throughout the whole tank. I also placed my glass diffuser right in front of the powerhead.

Yay for improving CO2 disbursement
