Thanks for the link, looks like them and I believe the rock came from FL, but not absoluteley sure.
The Rics are all different, it was the 3 for $15 deal SWF had a little while ago. We're running 4 x 65w pcs 2 10k & 2 actinic. First and last hour of cycle is just actinics for a total of 12hrs a day. Originally, I had placed them at about the same height in the tank thinking that they would all turn about the same color as they were diff, shades when we got them. Thought it may have been due to shipping stress, but it turns out that's just their colors. I believe that it mentions they come in varying shades of green on the shopping list and I commend SWF for choosing 3 diff ones to ship to us.
I eventually moved them to one side at diff. heights mostly to keep eventual real estate competition to a minimum and for a little more convienience in feeding on my part. I found it easier to feed 3 up/down than 3 spread across the tank. They appear to be doing fine and hoping for a little ric garden. I'll see if I have a pic of all 3 in one shot.
