I’m glad this was bumped. I was just talking with a fellow reefer about this yesterday. I have 4 hydra 52hds on a 240 gallon. 60 long by 36 wide by 25 high. I want to go with a ati. Either the 60 long 8 bulb or the 48 long. My buddy seems to think with the ati it would be overkill. But I think it would be great. Just haven’t figured out how I would set everything up
