Puffer is nice.
I'd remove the wood rimmed lip around the tank, it prevents access and only moderately reduces light spray.
I'd also raise the lights up to parallel to the roof beams.
Better to have lower intensity and better spread. You could make a planted tray in the rear for house plants and have the roots in the tank water.
Or just a row of pots for the house plants not linked to the tank also.
I'd likely get rid of the powerheads and get 1-2 Vortech's.
you can reduce the light overspray into the room and remove the wood lip by placing some wood to block the light spray coming down from the beams there, then stopping about 6-12" above the water.
This will reflect the light down and back. This will keep the front glass cleaner and allow much better tank access. Also will make the house plants grow better if you place them along that back edge. It would act like a large full length lamp shade basically.
You need hardscape materials.
