I started out with a package deal in the beginning...... and it came with a coralife skimmer. I later upgraded to an asm g3 and my other tank has an octopus NW150. I absolutely love the octopus skimmer. For the price it can not be beat. I would really consider NOT getting the coralife skimmer....I couldn't believe the difference when I switched...it was amazing. Hope that helps out!
