Got it today, first impression is, Im not completely blown away by it. Its powerfull but I guess I was expecting more for the price. Im sure once I give it a little time to do its thing and let the tank get used to it, it'll be fine... I was however, able to remove two of the maxi mods I was using, Im liking that. Took a little while to figure it out but once I was able to sit down with the manual, it was piece of cake. Im gonna be trying all the modes availble one at a time, I think Im going to like the short pulse mode the best... Im running it at about 3/4 power and it seems to be working well on a 3' tank. Ive noticed slightly better polyp extention already and I bet it gets better over time once the corals get used to the new motion... Over all, Id say it was probably worth the money and I would recomment it...
