I just wanted to add. I had a Fluval G6 i was going to use as a water Polisher only. The canister filters hold a lot of Nitrates if you don't clean them out weekly. I would use a sump. I have a 110g tall tank with a 40 gallon sump. I use a reef octopus skimmer. Go simple as can be to start. Learn how to test your water and adjust it to what it should be. Don't get into a hurry!!!! I ordered rock from Marco rocks. I didn't get live rock. After you do your aquascape add a few piece's of live rock to your sump. It will work. Being in a hurry wont work building saltwater tanks.
