I'm thinking of going with an EM200 on my 100 gallon mixed reef with a 40 breeder fuge. The skimmer is rated for 240 gallon aquariums. Is going with the EM300 which is rated at 340 gallons overkill? It's not much more expensive, it would certainly fit in my sump and I like the idea of being able to stock my tank a bit more. Is there such a thing as over skimming? Please advise.
