you need a vacation, i dont want to have to pick that tank up till next year, lol. hears, beats me, i use the unbreakable marineland, i think marineland ones, my 225, with 57 sump is using 2 of those, but then again im running halides on it, marine freak and all. as far as pumps go, you can always reduce down the tubing size, you may want to check, those holes may be set up for bulkheads, in which case it may be alot smaller tubing than you think, 1.5" pvc, takes like a 2.5" bulkhead hole.
PS. i do want the tank, but only when you decide that you dont want to move it lol. i could never take an enthusists tank, unless they had other plans
