Review on 🐠 Jebao DCQ-10000 Aquarium Water Return Pump - 80W, 10000LPH (2650GPH), Controllable, Wave Function by Lara Kaye

Bought this pump to experiment with a submersible DC pump in my 350 gallon fresh water tank. I have replaced 2 external GENx-40 pumps with this single submersible sump pump. This pump is virtually silent. The old pumps literally sounded like a whirlpool in my living room. With this pump I only hear water running into the sump. While I'm surprised by the performance of this little pump, I think I might need 2 of these pumps for my application. My system comes with 3/4 return which doesn't help, but I may need even more return than this pump provides. But if your tank is 250 gallons or less, that's probably more than enough to make for a return on investment.
