Electric Adjustable Flow Garden Sumbersible Fountain Pond Filter Silent Pump (2100GPH)

I pump 40 gal of RO/DI water from my basement to my first floor into my 120 Gal aquarium for a water change it takes less than 15 min, Thru a clear 40 foot 7/8 ID braided hose that I bought from ace hardware, Great product, gives you a lot of different fittings for hose sizes, and it has great flow control, make water change fast and easy.

The media could not be loaded.  Good pump. Plenty of volume. Has a good head. The water outlet is about 6 ft above the pump and still getting good flow. Now I have no idea how much water is being pumped at that head but it works great for my application.

using the pump to move water thru my koi pond heater, being in MN it gets cold. Not sure what the lift is between pond and heater, but my heater says it is receiving 12.5 gallons per minute. which keeps the heater happy and the koi at a constant temperature.

it's been on for 24 hours. Really not anywhere near 2100 gph, maybe half of that but I was expecting less than advertised flow so I bought the bigger pump. For the price it was a good deal. Will it run more than a day? Don't know yet. Will revise in a few months if it lasts that long

I am happily surprised so far. I have a 5 tier waterfall and pond. I replaced a 150w 1900 gph pump that burned out. The new pump uses 70w. With the flow adjusted to minimum it is almost too much. I could have sized down one. I have run it 8 hrs a day for two weeks with no problem so far, and the store bought replacement units were all above $140.00.

I feel this pump moves the most water for the price of any pump I've used. It's perfect for my mid sized pond. I even had to turn it down. It's been reliable, and doesn't get pluged up easy

For the price and its adjustable, I can't believe the power it has.... not bad

Works great, but would prefer the intake and out flow be parallel rather than perpendicular to each other.
