I have a brand new 150 gallon rimless tank that has never been out of the box. Shortly after I got it I also learned that the house I was renting would be selling in the next couple years, so I held off. Now the house is selling and I won't have space for a 150 on top of the others tanks I have in my new place. I just have the aquarium, no stand or sump.
Let me know if you have any questions.
