Are there any recommendations for sizing a skimmer in conjunction with a scrubber? I recently replaced my DIY ats with a Turbo L3. My current skimmer is an over sized cheapy that came with the tank, and with my DIY scrubber I got very little production out of it with my nitrates being .44 mg/l and my phosphate at .03 mg/l. And that was with a small amount of carbon dosing. I imagine with an ATS you'll get better production out of an undersized skimmer but I'm not sure just how undersized I should go.
