With so many manufactures out of the market, I'm starting to wonder if the only option is custom. I'm looking for a standard 180 gallon internal overflow. The only thing I can find that is still available is Aqueon and Marineland. I currently have a Deep Sea Aquatics. I love the tank, its only a 80 gallon though. I wish they still made tanks as they had three drains for the 180 which i feel safe with. So my question for you all is do you know of any other companies making a 180 with an internal overflow other than Aqueon or Marineland?
