Review on 🐠 PULACO Mini Submersible Water Pump: Powerful 50GPH Flow for Aquariums, Fish Tank, Pond, Fountain, Hydroponics by Elizabeth Thornton

It worked, but it worked great in my 3g shrimp tank. The tube looked like it had some weird flakes on it over time, I took it out all the way, rinsed and gave it a good rub before putting it back in the tank (slippery, so maybe algae?). Unfortunately today, 2 months and 5 days after receiving it, it stopped working. I turn off the pump when changing the water and when I turn it back on it hums and vibrates but no water moves. I tried changing the power setting up and down but the water still wouldn't come through. I put it in a separate bowl and shook it while running to see if I could get some of the seaweed off, but that didn't work either. upset.
