A skimmer is probley more inportant in a FO as the tend to be messy eaters and you want to remove as much protein as possable before it breaks down in your tank. Also depending what you keep for fish they can and will eat your clean up crew so removing the extra protein is important.
75 to small for most of the fish unless you want all small fish i would'nt bother,the bigger the skimmer the better how would you like to swim in a toilet

I have a 65G FOWLR and have a skimmer for it, but have been having trouble with the airstone of late, so it hasn't been running. I find that without it running, the nitrates are at a pretty constant 20, despite a weekly 15 gallon water change. I'd say definitely run the skimmer. It'll be less work for you.
That's clearly not true, because many many FO tanks are run with no skimmer without problems.
I'd say skimmers are very good filtration for a FO tank, but not the only option because wet-dry's and canisters, that create too much nitrates in reefs, can be used on FO tanks where nitrates aren't as toxic.
If you already have one, I'd probably keep it, and if you need more filtration because you add a lot more fish, then add some sort of wet-dry filter as well.
