The frags you bought were being grown under 400 w Metal Halide lighting (10,00k I believe)
The grow out tank is roughly a 15'l x 15'w x 3'd (Yes feet) tank. dont know how many gallons but large!
The halides are suspended about 3ft above the water surface and the frags you got were only about 2" below the surface of the water. There are about 6 or 8 light fixtures over the tank.
I am not making this up as It so happens I was there last week looking at the same frags while they were readying a shipment of them. probably yours.
For flow, the frags recieve a steady medium turbulant flow like a lagoon and the entire tank recieves a surge from an 2 large ATS's about every 30 seconds.
They only loss of a mont. I have witnessed their was an attempt they made to keep one in a 55 under 4x55w PC's.
If anyone is enterested, I am going over there sunday afternoon to take some digital photos of there grow out systems and display tanks. I may post some pics here on the board if it sounds like a worthwhile endevour.
I live just a few miles from Inland so it's my LFS and I get the chance to help them from time to time feeding their tanks and such.
It's a great learning experience and hey, who else gets the chance to play in over 35,0000 gallons of reef in indiana!
By the way, How much did the frags cost you and what size are they?
Later
