Color will change from that nice bright green to a greenish brown. Greenish brown is bad or any kind of green that's not that bright one. When it is ready to harvest it will be a dark version of the green it is now and you wont be able to see through it at all.
Looking good....you should check out the 454 purple bulbs, I loved having one in my T-5 combo and will be adding one to my current T-5's soon. Also I'm sure you already know, but careful to acclimate corals to the new lights.
I would like to take a min. to remind everyone we have iTrader....This is our way of protecting each other and being able to research who we're buying from before we buy. It only takes a second and it doesn't even need to be detailed. REMEMBER to give feed back please.
WOW! your a great ex, I think I would be there at 5am, just to be as mean as I could. Good luck w/ the move, and I have my fingers crossed for happy livestock on the other side.
Any one ever thought of registering and papering the corals? There'd be no question on lineage than. We could have coral shows and travel a circuit, which I'm sure is already happening.
