This is great. You have done some nice research and have your plan in place. So far so good. Here are a few tips that may help.
Sand - make sure you have between 4'' and 6'' of sand, or as an alternative, less than 1'' of sand. You do not want anything outside these levels.
Dry rock - you actually want to add some live rock at the same time as the dry rock. This will quickly speed up the process of the dry rock becoming live. If you look at my 180 build, you will see some nice pictures of the progress my dry rock made in becoming fully live. It doesn't take long at all. In a few months you will not be able to tell which rock began as dry and which was live. http://www.fishforum.com/saltwater-f...f-build-21979/
I used roughly 80% dry rock to 20% live rock. I ordered my dry rock from Marco Rocks The finest aquarium rock available, base rock, live rock, reef rock, marco rock, reef tank saltwater fish, live corals, Marco rocks, Fiji live rock, Tonga Live rock
You absolutely do not want to use the biofilter component of the Aqua Tech. The bio filter will directly compete against everything you are trying to accomplish. For now, until you can purchase the skimmer, just use activated carbon inside the AquaTech. Replace is frequently, every other week at minimum, until you get the skimmer.
