It looks great. I am getting ready to start my tank too..
BUT that sandbed looks pretty deep. I heard that if you make it that deep..you have a great chance of developing problems later one once things start to build up.
Someone here recommended 2 inches and if I need more for some of the species..just put 4-5 on the side somewhere for them..but not do that deep for the whole tank.
Anyone agree? I need to know this too before I start.
The rock looks great though. Good luck you ya!!
