Percula clown, Fuzzy Dwarf Lion, Royal Gramma, Blue Devil Damsel, and a Black and White Cromis. My only means of filtration besides the live rock is a tetra Whisper 30 gallon HOB. I also do a 3 gallon weekly water change. If you have a coral/invert only tank you def. won't need a protein skimmer. I myself am more of a coral guy. You could get away with a HOB skimmer and water changes just fine if you had some fish in there.

Lets not so quickly dismiss the success of a fellow hobbyist! There are different ways to approach this hobby. I have met a number of successful hobbyists with smaller sized reef systems that did not use a protein skimmer, but relied on water changes and even carbon filtration.
I do agree, however, that it would be much easier to duplicate a successful system with the use of a skimmer. Over the short term you would probably not notice much difference, but after several years issues with phosphate, pH, calcium, and alkalinity very frequently occur on systems that use hang on type filtration, as opposed to skimmers.
Given that the cost of a skimmer is not really a factor in the hobby today, with the online retailers offering incredible prices, I see no reason not to go mainstream and use a skimmer.
Now, this tank in question is a 75 gallon tank. There is no doubt that you will want a skimmer and you will want a good skimmer. So again, the question is, are you going to use a sump?
