9002 ideal flow rate?

I'm looking into my next 12gNC mod when I started thinking that by the shear design of the Tunze 9002 I wouldn't get that much more of a benefit in skimming by reducing the chambers water flow from the current rate. The pump recirculates and doesn't actively draw any water in.

I was looking at reducing the flow and enlarging the fuge to the whole third chamber and also reducing the flow to the 'sump' when I thought, is there really a point, I should just reduce the fuge.

So what do you think, would the Tunze skim better with a reduced flow?

Within reason, you don't want excessive turbulence but if the water surface is fairly calm I don't think there would be an issue with flow rate.

Thanks, the flow is only 230gph (MJ900 return) and it's more than likely slower at the intake slots. I didn't know if you had 'ideal' flow rates for the 9002.
