Wow, it only took me 3 days of reading to get me to end of the thread! But gotta say it was a great way of getting through grave shift at work.
Dennis, your tank is truly astonishing. It makes a lot of tanks I've seen at aquariums look mundane.
I have a few questions for you if you don't mind.
1. How many headaches did this entire build give you, like things not fitting or just fighting you through it all?
2. What would you have done differently?
3. For your rock tower, what did you use to hold the pieces together?
