My BIG Plans are for something small. As to expense, they're big plans. Almost costs as much as my big tank in terms of overall cost. But, Will be cheaper to maintain. So, my hope in 2021 is to have a nice beautiful AIO in my home office to have as my background for Teams meetings. I'm hoping a 35-45 gallon AIO, With sump or without. Decent lighting. That I could use my nano as a grow out tank for corals. Maybe do something funky with macro algae in the display. . etc.
