Absolutely gorgeous! I've got loads of 4' & 5' aquariums all over the place, but they're all fresh water. I used to run Co2 and do all the high light, lots of micro/macro ferts etc. but it drove me insane, I'm no chemist.
The thought of saltwater tanks terrifies me, its so exacting & full on chemistry so I admire anyone who even dares to try, much less turns out a masterpiece as you're clearly on your way to doing. Fantastic effort & very, very beautiful corals. I can only dream, or live vicariously thru yours so keep posting lots of pics
