It would be interesting to know what kind of follow-up and maintenance regiman you settled into once the tank got established. How large, and how often are the water changes? Does the filter system tend to keep the bottom clean by circulation, or do you need to vacuum? Any problems with condensation affects on your house structure? Did you experience any leaks because of settling? Is it expensive to heat, and would you recomend any type of special insulation. Have any suggestions for things you might have changed if you were to plan another grand tank like that one?
There is no doubt you learned some stuff along the way with a project like that. I'd like to do something similar when I retire. Nothing beats planning like listening to the voice of experience.
