Review on 🌊 Koralia 3G - Advanced Generation circulation and wavemaker pump by Jorge Gutierrez

UPDATE: This pump has been running for a little over a week and the water flow has dropped slightly. Its timer turns on and off twice a day, running for about 1 hour in each cycle. Today he did not turn on in the daily cycle. I took it apart, cleaned it and it worked again. The block is larger than expected, but it easily hides behind the scenes and against the black background. Runs very quietly and moves great on the water. The circulation in a 48 inch tank is great and moves detrite from the top of the sandy substrate around the tank well enough to help the filter pick it up, so far so good.
