We met RedStarFish during CIPS 2017 and, in addition to their fine manufacturing, we were especially interested in the new diffuser that they built themselves. A diffuser is a tool that spreads the bubbles in the body of the skimmer, right after the exit of the pump. It has a particular importance for the diffusion of the bubbles, and both the size and the “turbulence“are important. In hydraulics, the term turbulence refers to how often the water particles collide. The diffusion plates have a series of holes that serve to spread the bubbles in the area above. RedStarFish had the intuition to develop the simple design of the holes using conic-cylindrical fissured shapes. We really liked the result in the skimmers on trial in the booth. The foam seemed plentiful and well distributed.
The new RS-N Plus skimmers by RedStarFish
|Model||Recommended aquarium||Pump||Pump consumption||Dimensions||Aspirated air|
|RS-N130 plus||400-500 liters||HP-1500L||12 watt, DC 24V||200x190x485 mm||600 l/h|
|RS-N170 plus||500-700 liters||HP-2500L||25 watt, DC 24V||230x210x530 mm||900 l/h|
|RS-N230 plus||800-1,000 liters||HP-4000L||35 watt, DC 24V||285x260x600 mm||1,450 l/h|
I think the name of the model indicates the diameter of the body of the skimmer. The numbers RedStarFish declares seem to be very competent. The values of the aspirated air are realistic, so we wanted to suggest to you the recommended aquarium sizes too. But for hard corals SPS, you should probably consider half of the minimum value. But it’s the foam that is really the star here, as you can see in the following pictures:
The skimmers of the series RS-C
RedStarFish has, in addition to these skimmers, more traditional skimmers in the RS-C series. There are 5, with increasing characteristics.
