Skimmer set up for my 314 gallon

[Gripenfelter]

I currently have 2 skimmers. A SWC 200 and a SWC 180 cone skimmer. The 200 is good for up to 200 gallons but I'm not currently running it. The 180 cone is good up to 250 gallons light load.

On my old 120 gallon set up the refugium was so efficient I would hardly pull anything out with the skimmer. It would fill a 2 L waste bottle every 3-4 weeks. Or about 500 ml per week.

On my new setup I have the 314 gallon display tank, a 70 gallon refugium with 100 lbs of rock, a 50 gallon sump where my 180 cone skimmer sits, and a 30 gallon tank which my return pump uses to send water back to the display tank from.

So far it looks like the 180 cone skimmer pulls out 500 ml of goo per day.

At what point should I put in a bigger simmer or install the SWC 200 downstream from the SWC 180 cone?
