Personally I think you have a good setup, However you really need to start
reading up more to fully understand the background of Salt water. Its challenging alone just with Fish only. But when addign Corals to the tank you taking on a different ball game. I'm not saying that you don't know what you are talking about. But may be its me it seems that you are doing things as you go. I'm not saying it's wrong ,but you need to read more.
IMO doing a Reef tank its not about buying new equiptment and getting all top gear. Its about understanding Reef chemistry, knowing when to check when to add how long should i run This for. Etc etc.
You can run a setup with the bare bones GOd know, I have done it and most likely alot of us here who have more time in the hobby then me have done it too..
Maybe enhance your reading in the hobby more. read up on things that you wanna try. Every tank is different in its own little way. Now you can listen to me and the rest of the experince people who has alot more level then me or you can just ignore what I have to say and do what you want to do.
good luck on your decision.
and remember I'm a 2 min drive away and a phone call
