If I were you I would remove the bio reactor, do a search on here or reefcentral you will find tones of mixed results. Personally for me it was good to start and then caused problems in the long run.
I'm going for a more natural feel, DSB with mangroves & macro is a much better filtering tool.
Any idea on your final lighting, aquascape or fish & coral comp? Looks like it's going to be a wicked tank, will be watching for sure.
Your clowns will be fine btw, look at how the favias are doing! Watch early morning or @ around 1:00am, lots of open mouths to be seen.
