Wow, it looks like quite a production! Be sure the rocks are not sitting on top of the sand. The rocks should be on the bottom glass. If they are resting on the sand, you are asking for a rockslide and broken glass... Your clean up crew and fish will burrow, and your powerheads will move sand, and when the sand shifts the rocks will fall over. It has happened a few times to people on here, and you don't want to end up with the contents of your tank on your floor.
Thanks Biff! The rocks are dug way deep into the sandbed. The guys that set it up are from my local lfs. Actually one of them is the owner. They also do aquarium builds and maintenance. I don't think those rocks are going anywhere. They are the pros! Thats why I payed them the big bucks! :mrgreen:
