That is one awesome tank and fragtank setup!!! :drool:
I have the same stand and I also bought mine used. I rebuilt the inside of mine and I am not sure what wood they are made from but it was virtually impossible to screw anything into it. :-\ !!!
What a great job on the set up, I'll have to take a better look at the plumbing for future reference, looks very neat and tidy ! Nice that you've been able to plumb it down to the basement. The tank looks stunning!
