75gallon FOWLR, various shrimp, crabs, and feather dusters. I like the idea of having a wider stream, but the flow ratings to this different type of stream, have me confused on what size to get. Two 2's or a pair of 3's? any help would be great thanks. Oh these are the only things that will be providing flow. Thanks

I have two #3's in my 90gal. Should work great for your 75gal as well.

I have two 3s in my reef tank and it is fine.

Question though... since this is a FOWLR does it really matter?
