IMO the vid is NotVeryGood..
its is just a cheapo flip-video recorder. (very easy to use but not the greatest quality)
and if my hands were less shakey thing would get better.
i know its not all that natural with all the rocks pokeing out into open water but it adds a lot of dimention to the tank and was easy to do with the 10mm acrylic rod i used. honestly it looks alot better in the tank than i did on my frt porch, ha haa!!
i took all the rock out and placed it on the frt porch and started drilling holes and stacking rock. once i had a good base structure established i drilled a bunch of holes into the top of the main structure and put that part into the tank. then i just attempted to chose the coral that i liked and attempted to place them in ideal locals to provide it with the focal points/lighting/and water flow that would seem best, drilled holes and placed them ontop of the stems of acrylic pokeing out. (sorry about the compound complex run-on sentance, im a little sleepy)
