I looked at 1 of these one time. I think the bottom was drilled and plumbed to a canister filter under the stand. The light is a T5HO 2 bulb GLO light. I also thing it is all acrylic. I would check into the Red Sea Max tank that came out not to long ago for the that kinda money. I would personally Find a 75 gallon glass tank and get everything for 1/2 the price you would spend on that setup. JMO! Good luck!
