Tunze 9006 - 130$
It's rated up to 158 gal. It works fine, very little use, close to being brand new. Sparkling clean too
As you can see from the pictures, it's in great condition.
Here is a link to it on Marine Depot if you want to see the full specs.
The reason I'm selling it is because I don't have a sump and I got a HOB skimmer instead.
