Hydor Koralia Powerheads...which size to get?

[oddjob142]

I have a 92 gallon corner tank.  I currently have two maxi-jet 900 powerheads on it.  I am switching to the Hydor Koralia ones but I am not sure which ones to buy.  How much water movement is too much?  Can I just get one, or should I get two to even out the flow.  I really hate having my plants leaning in one direction...like they do with the maxi-jets...

Nano 240 gph 3.5 2" x 3"
1 400 gph 3.5 2-1/4" x 5"
2 600 gph 9 2-7/8" x 5-7/8"
3 850 gph 10 2-7/8" x 5-7/8"
4 1,200 gph 12 3-1/4" x 6-1/4"

Thanks...

The Maxjet 900 is 230 gph.

If that is blowing your plants around too much..then..I would get the smallest Koralia.

The nano

well...i guess the question should be better phrased:

should i get a BIG one (3) or should I get two small ones (1's)?  Is it better to have one or two?

nm...i decided on two of the 1's.  That way the tank can be more evenly circulated...
