I'm using a similar Chinese version of the LEDs you are using. They produce growth just fine lol. Also, with the amount of corals you have, you shouldn't have to be thinking about dosing. Dosing should only be done when you have a abundance of corals that are using up a available resource before you can replenish it via water changes. If you bump your water changes up to 10-20% weekly. You should be fine.
Also, one of the reasons your testing a little low on certain things could be the brand of salt you are using. Instant Ocean?
Also, a Copperband butterfly could of solved your Aptasia problem fairly quickly. Or a File fish.
And lastly, I would skip on Anthias. Unless you intend on being religious with making sure they eat enough, they will die. Might I recommend some Firefish? Fairly colorful, and easily visible once they are comfortable in the tank. And, for a schooling effect, BG Chromis? They are relatively cheap, and can get large enough to be noticeable anywhere in the tank.
