Welcome to Canreef!
I agree that dosing won't be needed yet. Wait until you get into some more advanced corals, and you WILL get into them eventually.
The only thing I really think is missing other than a skimmer is more flow. 1 Koralia #1 doesn't seam like enough flow for that tank. Round and Hex tanks are a bit of a challenge when it comes to flow. If it were my tank I'd add at least one more Koralia #2 or even a #3. It will help with nutrient export and your fish and corals will love it.
One question; what are you running in your Fluval?
