I would wait a bit. They are not pulling near the air draw they advertise right now. They are also changing the volute on the pump around too. I would wait til they get all of the kinks ironed out. Also, have you looked into the MSX 200? They are absolute beasts....I saw one running at Marine solutions, if I had a big enuf tank, there is no doubt that is what I would get.
And it is cheaper than the octo pro.
