VIVOSUN 800GPH Submersible Pump(3000L/H, 24W), Ultra Quiet Water Fountain Pump with 10ft. High Lift with 6.5ft. Power Cord, 3 Nozzles for Fish Tank, Pond, Aquarium, Statuary, Hydroponics Green

I use this as a transfer pump and for water changes, and it works really well. No fuss, no drama—just plug it in and let it do its thing. It moves water faster than I expected and hasn't let me down yet.If you're tired of lifting buckets like you're training for a fishkeeping strongman competition, this thing makes the job way easier. Worth every penny.

These are perfect for what I need them for. They work in my pond. They only last a couple seasons but for the price you can't beat it. Also. They are pretty tough. My pond can be quite dirty. I would say go for it. Also getting a mesh bag to put over it to keep the big chunks out of it helps a lot 😁

Good value pump, which has been running just fine as the main filter pump in my small backyard waterfeature/pond for the past 3 yrs. The thing claims 800 GPH at 24W, but if you look at other similar pumps with more watts, they all have fewer GPH. This does move water, but doubt its 800 GPH... Still a good value otherwise.

This pump was fantastic for my use with great water flow. I tried two different pumps based on a simple evaluation of water lift. Forget that. I only had about a 3' lift but even a 264 GPH pump just barely bubbled. This pump gave me what I wanted and more which allowed me to dial back versus running at full flow. The pump appears to be well built and good quality. I highly recommend this pump for your small to medium fountain needs.

Sound level is very good for a pump of this flow. I bought it to use in a Low-Pressure Aeroponics setup - emphasis on learning about LPA without breaking the bank. The outside casing makes it look like about 50 other water pumps carrying various names at similar price points and advertised flow rates, but it puts out more than twice the water of a nearly identical-looking 640GPH pump, and my misting heads can be tightened enough to produce very fine mist without stopping the flow altogether.This little 800GPH pump is likely a little less powerful than it claims, as the lift height is stated at 10', and at 6' the water flow is quite restricted. But for a small, cheap "testing" setup, it works great even with 10 misting heads on 1/4" PEC irrigation tubing. The fittings seat and seal well on the pump outlet, and a spare suction cup is included in the box. Also of interest, the noise level is actually lower than my 640GPH pump.Wattage is as specified, with very occasional increase/decrease, and connecting it to my 1500VA/900W UPS system barely increases the load, dropping the 450-minute "unloaded" reserve capacity by just 12 minutes. Running only this pump on it I would have more than 7 hours of water flow if the power goes out.The pump itself is about twice the size of the 640GPH, and more than twice the weight. Mounting it to the side of a reservoir requires an absolute minimum water depth of 5.5", and with a "Y" splitter in the outlet for balanced pressure in a looped irrigation setup I recommend placing one of the nipples on the pump outlet and using tubing to connect the splitter so you can lay the splitter flat in your reservoir and place the pump upright on the bottom as there are water intakes that must both be submerged on both ends of the pump. Using 1/4" irrigation tubing without a cap and free-flowing, the inlet flow control at the front makes no noticeable difference in the amount of water flow, so if precision flow is required you'll need inline valves, but for my setup, adjusting the misting heads is enough.So far, I'm quite impressed with this little guy, and no longer worried about finding my plants dead from lack of hydration or nutrients. If it lasts awhile, this will have been a great buy - one I highly recommend for smaller LPA hydroponics setups or even a 3-bucket tower or up to 10-bucket Dutch Bucket system.At this price point, I can keep a couple of these on the shelf in case of failure, and if they last 6 months or more in use, they'll be well worth the cost.

Good little pump with very good flow rate.The pump is slightly adjustable with the knob on the side of the pump body.Very easy to remove a cover and clean the pump intake also.Would recommend. I am using it for a home sluice water supply. (Gold recovery)

This pump in my aqua phonics set up. It’s awesome, but I will strong pump. It does have adjustment valve. It’s almost too strong for my 10 gallon tank. It’s awesome. It works well. I would highly suggest. I have two of these exact pump.

Good pump and relatively strong but be careful with the details offered in the description. The description states that the three threaded to barbed hose connectors have a thread of 7/8-14 UNF. That is false! The threads and the pump female threads are a fraction smaller than a 7/8-14 UNF thread, so if you wanted to thread another 7/8-14 UNF adapter into the female threaded output port it will not fit. I have had and been using the pump for 3+ years and it is still operating flawlessly. So, the pump with its provided adapters are fine, but do not go by the provided info on thread sizes as it is NOT ACCURATE.
