1-how did you get your rock to stay up there like that
2-after the success I've been having with T5's on my 80 gal SPS tank I'm currently researching the best way to modify my existing 265gal from all Kessil Pendant lights to add T5 bulbs. or VHO. I'm looking into long bulbs or 3 sets of short bulbs because I have 2 braces up top.
How much do the fixture run for amd do yhey come in 72 inch
