Equipment advice for a 120+ gallon setup

[McFish]

Hi there,

I've been running a 30 gallon planted community aquarium with a Coralife light and CO2 (regulator w/ needle valve only - no ph) for a couple of years & now I'm looking to upscale to a similarly stocked but much larger built-in unit.

What are everyone's recommendations on 'must have' & 'nice to have' equipment once you move up in size? I'd also appreciate any comments you all might have on the pros/cons of different suppliers - are some more reliable, quieter, not worth the cost vs features, etc?

Thanks for your thoughts!
