My daughter's 30g cube nem tank needed an emergency light replacement last week, so i picked up a nicrew, i have been very impressed with it so far, especially at the price point. The spectrum is great. They have a 3 lens fixture that would be good for a single light option. Only downside is that it needs an external controller for fine tuning.
I have 2 meridian 11's over my 75 stick tank, those are fantastic and have been pumping up the SPS growth, the app is legit and i would definitely recommend, youll probably want a meridian 24 for a 32" tank.
The other option is to get a couple strips, 2 or 3. quanta helix strips are really awesome, but don't have a built in on off. The AI blades work great but are kinda pricey for what you get. I have also heard good things about the new AI Edge44 but don't have any hands on experience with them.
What all are you interested in keeping, just softies and gorgs? My suggestions would be sufficient for most anything, you might could get away with just 1 strip for those
