250 is very adequate for a 180, I would not go as high as a 350 unless your tank is over 200+++

The 250 is good up to 250 gallon on medium stocking.

I think I just found a new skimmer for my 155 Bowfront / 155 sump / 30 fuge / 30 frag tank / 10 mangrove fuge build (total of 350 gallons of actual water volume)

The 350 looks awesome!

Well it's a 180g tank but adding the sump and refugium it's more like 250g. And i have lots of well fed fish
