VIVOSUN 660GPH Sub Water Pump for Fish Tank, Pond, Aquarium, Hydroponics | 40W Submersible Pump, Water Pump with 5ft Power Cord and 4 Nozzles Blue

Works great. I use it to change water in fish tank, and get the water off the pool cover in spring before taking off the winter cover.

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.

Very good pump. Good flow and pressure. Would buy again.

We have a small patio fountain that came with a pump. The pump failed and I bought this to replace it. I knew this pump would be larger but I wanted to get a higher volume pump and also I liked the idea that this was a bottom dead pump. To get this to fit, I had to remove the aqua cover. The good news is, the cover is simple to remove and does not provide any real purpose other than the handle and possibly protection from if you drop a rock or something like that on the pump. I wasn’t worried about the accidental damage and found the pump to be more discrete without the aqua colored cover. The inside is all black and completely sealed. My favorite thing about the new setup is that the fountain can run almost dry and the pump keeps on going since it only needs about 1/2 inch of water to run. The previous pump required about 6 inches of water because the intake was on the side and was mounted much higher. One additional change I had to make was to add a filter since this pump does not really have a pre-filter. I went with a mesh bag purchased here on Amazon and added bio balls to the bag, also purchased on Amazon. This setup works much better than the small pre-filter that came with the old pump. The water stayed much clearer this summer.

In conclusion, if you're in need of a powerful, versatile, and reliable submersible pump for your aquatic setup, the VIVOSUN 660GPH 40W Submersible Pump is a solid choice that delivers on performance and value.

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.

Easy Peasy !! Outstanding and Quiet as a Church Mouse Emptying the pool Highly recommendex

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.

I don't have an aquarium. I bought this pump because of the gallon per minute rating and being able to suck the water from so close to the bottom. It runs very quietly and has the output that it said it had. I love how small, quiet and powerful it is. I wish they had and option to send some flexible hose with it though. Using a garden hose makes it very clunky but it's not the pumps fault. Using a 1/2'' hose gives an exceptional flow rate, way more flow than my kitchen sink faucet. I will buy another one in a smaller size for a project I am currently working on.

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

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