IMO Skim and overskimm, it is much easier to add food nutrients to water then to take it out.
The trick is to keep lighting to your corals at required level not more , meaning if you only have some LPS don't have too much light or you will have algae problem. If you want high light demanding SPS then you need more light and cleaner water or you will have hair algae (no one is different), skimmer is one of the easiest ways to keep water clean, ORP high and water oxygenated.
I have never seen a skimmerless good looking tank full of SPS with good colors in person i have only heard about it .
But if you decide to go without the skimmer let us know in a year how is it going.
