@tdileo what is your goal for the tank?
Mainly fish?
Corals down low on Sand?
Do you have an idea/vision of what you are going for?
A tall tower makes it hard to place corals I'd think or limits what you can add to your display.
And you've only got 2 caves or hideouts for your fish. Is that enough?
I'm not a minimilist when it comes to rockscapes so I'm probably not the right person to give an opinion but I did have questions.
Also, is that enough rock for filtration? Are you planning to put a lot in your sump?
