This is a Super Reef Octopus XP1000SSS 6†Space Saver Cone Skimmer, in excellent condition, comes with an Reef Octopus Stackable Neck Extension and a Percision Marine skimmer stand.
I have been getting people ask me about the neck extension, it's more of a body extension . As you can see in the picture it's the same size as the body not the neck, so it's giving you a bigger chamber and more foam building space.
