Hey I bought this beauty for my salt tank, but due to space concerns had to let my salt tank go, didn't even get to start it up:( I wanted an overkill protein skimmer for the 90g so I bought this terminator 2 which was the best I could find, its for up to 300 gallon tanks. Its brand new in box ready for a good home. Text me to check it out! Browse my other fish goodies also!
