VIVOSUN 660GPH Sub Water Pump for Fish Tank, Pond, Aquarium, Hydroponics

I used this water pump for my fountain, and it works great. It has a strong and steady water flow, was easy to install, and has been working very well. I’m very happy with how it works in my fountain and would definitely recommend it.

Just came here to say I bought this in Aug 2024 for my koi pond and it has been an absolute work horse. Even after leaving it running while there’s no water it still turns back on like a champ. Drains mucky ponds and pools quickly! Would buy again. Great brand.

Works really good until it does not work. Had this well over a year, weakly use to pump 20 gallons per week. Tried other brand looked nearly the same. That pump lasted a couple times. Going back to this one.

I use these pumps for my fish pond filter. It works great and have no problems. The price is right and the quality is good. I give this pump a thumbs up 👍.

This little pump empty my 500gal. pond no time

The title says it all: Powerful pump but it will raise your water temperature by several degrees. I have been using this for an airponic tower garden. It was powerful enough to pump water up to 7 feet and drive 5 sprayers. Unfortunately, it raised the temperature of my nutrient solution by about 20 degrees F by the end of the day. Not a big deal in spring but in summer the water spraying my plant's roots was up to 115 to 120 degrees F. I bought a smaller version of this pump, about a third as powerful, and it also pumps as needed but it only raises the water temperature about 5 degrees. Size your pump appropriately! You wouldn't want to cook your Koi.

I used this one time to try and clean my fish tank (no substrate, aka no gravel or sand or anything on the bottom that could get stuck in the pump) and it never turned on when I went to use it the second time. There was no reason it should have stopped working, because i ran it for 30 minutes the first time, unplugged it and took it out of the tank and stored it in a dry place under the tank stand, and came back 3 weeks later to do another water change, and the impeller wasn't turning when the electricity went through it. Never ran it dry (never plugged in when the pump was out of the water). Don't waste your money. By the time I tried to use it the second time, the return window had closed

It works well, and is quiet at first (almost barely audible!) but after three days of use it is now louder than my air conditioner.

Just arrived and I am very happy. I’ve been using a manual siphon to clean my turtle tank and pick up settled gunk, and water changes (150gal) it took a lot of time. I used this pump for the first time and it took a quarter of the time to get every spec of gunk and to drain the tank. Hose/piping not included but already had some and it came with different hose adapters and one of them fit perfectly. I will say that if the gunk is to big it gets a stuck and won’t go past the propeller, but I unplugged it removed the gunk and worked great again, took 30 seconds, not to big of a deal for me. As long as it keeps working I’ll keep giving it a 5 star

Es usada para rehusar agua de lavadora para lavar el carro, hasta ahora su funcionamiento es bueno, no ha fallado.

Muy buen producto yo lo utilizo para sacar agua de una pila y llenar la lavadora.

Very happy with this pump. I use it for my back yard pond and works great!

Nada recomendado, se descompuso pocos dìas despuès de instalarlo y ademàs medimos el caudal y da menos de 400 litros por segundo, totalmente engañoso.
