Bio wheels are like any other type of
mechanical filter. They
trap detritus and keep it in the water column so are a perpetual source of nitrogenous waste.
Coral, especially SPS corals should be in as pristine an environment as possible, as free of any type of nutrients as possible, including nitrogenous wastes. Bio wheels are fine for fish only tanks, fish can handle nitrates, but they are not good for reef tanks.
Could you keep them? Perhaps. Will they thrive in your tank? Not likely.
How much LR do you have? If you have 20lbs or so of LR that would provide enough biologic filtration, and you can go with what you have, minus the Bio wheel.
I am not an expert on the lighting, but the wattage seems enough. Most SPS folks dont like PC's though, I am not sure why this is. SPS tanks also need a lot of flow, you might have enough with the PH's and the skimmer, I am not sure.
Probably the next person will tell you that your skimmer isnt good enough either, but it works.
