BioCube failure, new start with 45 gallon rectangular tank?

[JTP424]

That is all music to my ears.

For filtration/flow in a 45 gallon rectangular tank, I'm thinking (i) a Tidal 75, (ii) a HOB skimmer (like aqua maxx), (iii) two Jebao SOW-4 wavemakers, (iv) live rock, and (v) live sand. Am I missing anything?

For lighting, since I'm not planning to do any corals, any recommendations on a relatively inexpensive light that can be put on a schedule and perhaps controlled remotely? The tank is 36" long.

Sounds like you got a solid plan!
Regarding light.... I run my freshwater off a switched one plugged into a bluetooth plug. I can run it off my alexa etc. I'll let others chime in on actual lighting
