Not trying to be critical just offering an opinion but you may want to add at least one more power head or a couple of small ones to move water around your rock etc... Any dead spots meaning low or no water flow and you'll see red algae show up. As for your skimmer I had one before and liked it but I added a wooden airstone and a small air pump and I liked it a lot better. If you keep your feedings down, and do water changes you should be fine with the skimmer as is.
Keep us posted as to how things are going.
