Review on Simple Deluxe LGPUMP80G 80 GPH Submersible Water Pump: Ideal for Fountains, Ponds, Aquariums and Hydroponics, with 6' Cord and 2 Threaded Nozzles - Versatile and Efficient - Black, 1-Pack by Lisa Green

These are really great little pumps. I have one on a 5g reef where the HOB filter is not providing enough flow. The fact that you can control the amount of flow is amazing. I also have one in my palette that's flipped most of the way down to give my chaeto ball a nice smooth, safe drape. The long cord is a nice bonus. I hate power heads/pumps with short cables - very annoying. I've had one running for at least a year so they're built to last. Easy to clean.
