I had purchased 6 maxijet sureflow 1600 mods and 2 of them were not quieting down, even after over a month. So I gave an email to Algae Free telling them my problem and they sent me 6 upgraded replacement impellers at no charge. These impellers were specifically made to be used with the MJ1200 and were much larger/ more powerful then the original. Unfortunately, these upgraded power heads were all attached to my wavemaker which ended up snapping 4 of the 6 ball swivel mounts they were attached too in less then a week.
Lesson learned, Algae Free has great customer service. Unfortunately I was the guinea pig for their new large impellers. **WARNING TO ALL** Algae Free Sure Flow Mods now come with both the black (weak) impeller and the white (powerful) impeller. If you have them connected to a wavemaker DO NOT USE THE WHITE IMPELLERS while connected to the rotating ball mount they provide, or you will find your power head in your sandbed in short time.
