FREESEA Submersible Water Pump For Fountain: 900 GPH 60W Adjustable Sump Pump For Pond Aquarium Hydroponic

Great little pump. Use it to transfer water for aquariums and I use the 1/2 in. outlet adapter. Pick a clear tubing up for it at Lowes for under 7usd 10ft long. empties 50% of aquarium 20gals in no time. I use buckets and drop it into the bucket to replace what water I remove and it's just as fast both ways. Would recommend to anyone wanting to save time on water changes.

It's perfect for water changes in my 75g fish tank

I bought this to replace the several cheap pond pumps I have used in the past to drain and fill my aquariums. They would burn out or break within a few months. I bought the 845 gal and it’s plenty enough to serve that purpose. It pumps fast and strong, making my water changes way faster than they have been before. It drains water well below an inch which makes moving a setup that much easier on the back. I don’t fear this one breaking like the others. The first time I used it in my 40 b it sucked up pea size gravel and shot it out the other end without any sound of grinding and zero damage. That only issues I’ve noticed so far are the short power cord and the lack of a low water cut off. This would make a good sump pump as well as its very quiet and absolutely powerful enough. Would give 5 stars if not for the cons I mentioned

This little pump works AMAZINGLY well...especially for the price. Used it to empty my in-ground spa. SO glad I purchased.

Works great in our turtle tank!

Great pump for the money!

Not as strong a pump as they say it is. Ok for a larger tank.

So I live in Texas. About 2 weeks ago, mid-February 2021, we had the worst winter I have seen in my 49 years. For my friends up north, a typical heavy snow and cold week. But nothing in Texas is prepared for 8" of snow, 5 days with temps in the single digits to teens and wind chills below zero. We don't even have clothing for such an occasion. It's usually between 58-75 this time of year. We hadn't even seen a real snow in 5 or 6 years. It is rare, normally 1.5" and typically lasts a day or two at 25 to 30 degrees. Half the state lost power, including myself, for 4 days straight. Pipes froze, busted, and flooded homes, car pile ups in the city, some people literally froze to death and some are still picking up the pieces.I'm one of the latter. Our septic system froze and I still haven't gotten it going. It is a 4 tank 2000 gallon system, Aerobic System. The pump is out, no plumbers are available and the local supply of plumbing parts has been decimated. Our system was full, from flushing water lines, not realizing it was not on and filling up. I needed a sub pump to empty the system from the gray water tank. (for those that don't know, this is chlorine treated waste water, no solids but there is small sediment.) There were no dirty water pumps to be found and they were $160 dollars at the low end. I searched AMAZON as a shot in the dark, hoping a Prime item could get here quickly. I gave this little $20 pump a shot.It ran like a champ, pumping out the system over several hours. It still works perfectly. I'm using it to keep my household operating, until a plumber can get to me and get a new pump ordered. You'll see in the picture I zip tied a piece of mesh tightly to the bottom, just in case anything substantial was in that water. I connected a cable to the handle to pull it up. I sent it down to where I had no idea what was below and it just keeps pumping! Whenever I need to clear the system after laundry, dishes or baths, I just plug it in.It is still sitting down in the abyss. It has saved us, because there are no close-by laundry mats or bathrooms to run to in rural America.This Little Green Machine is doing the job of pumps 5X its size and 10X it's price range, effortlessly.I don't know how long it will last, but a week would be worth the money and we are starting week 2.Get yourself one!
