Help decide


New member
Hello guys, I am new at this and just beginning my saltwater/reef journey.
I have 125g tank and 40g sump. Cant decide on skimmer: Aquamaxx EM200 for 240g or Aquamaxx EM300 for 340g. Is it too much? Over skimm?

I just ordered an EM300 for my 215 build. I think you'll be fine with the EM200 if you want it.

I like to go a bit over rated on my skimmers.

I have an EM200 on my 135 and it's plenty.
I chose the EM instead of the Cone2 because of limited space in my sump.
