@smitty, thanks for the complement. Always willing to give advice as I have been doing this for a long time. @ nxb161, the current tank is in my finished basement which also serves as my man cave. No structural issues down there! The new tank is also going to be a mixed reef/fish tank. It will be 30" deep. It will be in the center of a room so it can be viewed on all sides. (either this or a pool table!) the returns inside the tank will be in the center, that way, I can set my rocks in the center. I want the fish to be able to swim all the way around the tank. I cant wait to set this thing up! Putting the additional fish list together.
