I haven’t used sand in years — all my tanks have been bare bottom! It’s very easy to crank up flow and don’t worry about detritus traps. However, it’s gonna to take awhile (a year) to mature vs sand.
Cycle: I just use a bottle of Fritz 9000 for an instant cycle. If you have some LR from other established tanks, that would help speed things up.
How big is the new tank?
