wow i didnt think they were duncans. i want to try to mimic something like his tank, but he has a 150g. i thought they might have been duncans but never seen them like that. i think he's using a vortech or 2. on the other tank he maintains for Pratt, its a 240g SPS tank. and that thing is unbelievable. you can go sit at the couch infront of it and just do your hw there. i didnt know the 240g had like 2-3 vortechs until i saw his youtube video
