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 have numerous 100+ gallon tanks as home for my cichlids collection.I use these pumps as circulators to keep a circular current moving across the bottom of the tanks.This prevents waste from settling as well as provides current for the fish to swim against (they LOVE that!)I think I've purchased 6 of these altogether now.. very satisfied with them.Typically, if small, Chinese made pumps like these last 12, 18 months, I call that a win. These are over a year old... still hanging in there.

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.

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.

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.

Very powerful little pump. The nozzle is submerged and still sends a column of water a foot in the air. Used on a small water feature and, after 5 previous fountains, I’ve found what I’mmlooking for…a product that actually does what it’s advertised to do.

I used this pump to empty my above ground pool. It worked great for the price!

This was more pump than I needed, but I could still use with slight modification of application. If you need a powerful little pump, this one is for you.

Great water pump, functions as it should. Only reason 4 stars instead of 5 is the temperature of the running pump. If you're using it just to transfer water it is a dynamite pump. If you need to keep it submerged and constantly running, expect water temps to increase due to pump getting warm
