aquaclear 500-help

[Cliffz]

Folks,
Im getting ready to hook up my CO2 next week. (when I get shipment from Rex Griggs)
Problem-My Aquaclear 500 filter really moves the water in my 55 gal. It has a high flow rate even when set to slowest rate. What can I do to minimize the turbulence this huge filter creates?
I am under the impression that water movement is not good for Co2 absorption? I am going to purchase one of those Red Sea Reactor 500 vortex diffusion chambers for absorption.
My eventual goal is to have no movement in the tank--IE-getting rid of airstone, slowing AC500 flow.
Any suggestions ?
Thanks in advance for your patience.

Raise your water level up high enough that there is no splashing. That will cut down on the amount of gas exchange at the surface...

I have put a sponge over the intake of mine, it has done the trick.

Folks,
I cut a cube out of an AC filter foam and dug a hole out of the center for the intake pipe covering the entire intake nozzle including the bottom tip. --Didnt slow down the flow much at all. its apprx 1-1/2" by 2" rectangle .
It does work well as an in-tank pre filter catching plant and other "stuff"!!!
How about changing the impeller to one from a AC300 or 150? Same size impeller?
Mine is an AC500.
Thanks
