This is a No Joke Wave Maker. Adjustable to suit your tank needs and powerful enough for my 210G on its own! Comes in a smaller model as well.
Wave Maker – 3400 GPH
This Wave Maker is very powerful, used in My 210G tank as a stand alone wave maker on top, angled upwards for surface agitation. It is powerful enough on its own and will pull all the detritus towards it. Best used on same side as filter intake. Wavemaker has adjustable power settings, adjustable pulse rates, frequency, night and feeding modes. Comes in a smaller 1000 GPH model as well.
