For Acro dominant with RSR250 you’d probably want 6 or 8 bulbs. I have (4) 24” tubes (should have gone with 36”) split between 2 reefbrite T5 retrofits with 3 Radion XR15s in the middle over my Reefer 250. The T5s and LEDs combined are 18” from front to back. The Reefer 250 is about 19” front to back. There may be some light spillage with a 6 or 8 bulb fixture but you could move the back of the fixture closer to the back wall.
I don’t know what PAR a 6 bulb 36” T5 would provide, but a 6 bulb ATI, with an LED strip or two eventually, is something I would’ve tried.
