I just got this newsletter this morning from Ocean Aquatics that related to these powerheads. If you are considering getting a Koralia or something similiar to upgrade from a Maxijet 1200(which I just did

), you no longer need to. Good luck with the sale. With these new upgrades, I don't think you will have a problem.
