thats crazy same dimensions as my soon to be tank but yours is 5 gallons more.
anyway. two of these in my 125DT might be pushing it, cause i mostly have softies and some LPS. so that much extra flow might be good, or might not. we'll see. however. i am still going to make them for any future tank i have. im weird like that. eventually one day i will want an all SPS tank so these are good.
