Powerhead/Pump recommendations for flow

I'm looking at getting a powerhead to help with dead spots and flow.

I checked out Guitarfish, kris' blog and all his tanks have a powerhead or two for flow.

My tank is 36" long and 18 wide - I'd like to place one at one end and push the water back towards the intake. Would the Koralia Nano 240 or 425 be a good choice. I have visions of my rotala being bent sideways and fish being blasted out of the water - What do you use in your tanks?

(alternatively, a larger filter than the 406 could give me more turnover and thus more flow)

I have a koralia nano 240 in my 29gallon tank, and it does a fantastic job. I have it placed so that most of the flow is hitting the back glass. This way it doesn't bend any plants, and still circulates water around the tank.

Well, it works. Two for one - what little surface film disappeared and increase surface agitation. It's not too strong - I think the 425 would be too much for a planted tank that's 36" If this were 48" the 425 would be a better choice.

I've parked it at the right in back facing up and it helps churn the water in a circular fashion. I have noticed what hair algae that appeared on the leaves in that area is gone. It was a flow dead spot.

I have used the JBJ circulation pumps with good results, they are a little smaller that the Hydor models and the price is right at Marine Depot, mine were 550 gph and they have a wide gentle flow and 2 pumps with a wave maker was about $70, you can also buy them seperately and they have 1600 gph model as well. I used 2 in my 150 with good result with one near the surface and the other near the substrate and I could have used the larger models without blowing my plants over but my tank is 48 inches long, good luck.
