hygger24V DC Water Pump Inline Submersible Saltwater Aquarium Pump with Controller Return Pump for Sump Tank 2650 GPH

Absolutely LOVE this pump. It's been in use since Sept/Oct of 2023 without issue, and has honestly been rock solid. My previous return pump (Reef Octopus VarioS-6 ), cost me about 4 times as much, but refused to keep a consistent flow for more than a few days. I had to keep adjusting the gate valve from my overflow to keep my sump water level where it needed to be, which as you can imagine was infuriating. Even after cleaning it, the flow would be ok for a few days then start dropping.Anyway, I honestly didn't expect much from this pump - but man was I wrong. It's dead silent, has never had any issues whatsoever and has been amazingly consistent for me. If you are on the fence, give it a shot before buying one of the overpriced "premier" pumps. I will 100% be buying another for a backup, and if I start up another tank, this pump will absolutely be on the build list.

This pump is in use in our 400+ gallon outdoor pond. It pulls from an in pond skimmer, and discharges to a k1 bio filter, then through a UV light, finally discharging to a waterfall. I mounted the control pad beneath the railing of our deck overlooking the pond (had to buy an extension). From the deck we can pause the pump during feeding, or pause the pump to clean the skimmer basket - after 10 minutes the pump starts back up without any issues. The variable speed has worked great - when we added the UV light it created a flow restriction, but all I had to do is drop the pump speed a little bit. This pump works great, we love it!

Long time aquatic hobbyist (Reef tanks, Fish only saltwater, Ponds, Waterfalls+++). I've found all pumps "hum" over the years; not this one. This pump is inaudible! I couldn't tell it was running when I plugged it in until the flow of water started down the waterfall. The flow regulation is a cool advanced feature but the complete silence still astounds me.

Have been involved in the saltwater aquarium hobby for a loooonngg time. As anyone who has… you’ll agree… a lot of the products being produced these days just isn’t on the level of what was #magdrive/danner.Purchased this pump to replace (no lie) a 20 plus year old magdrive 1200 that went up.After a lot of reviews… as well as 1-2 disappoints… purchased a hygger. Well made, super quiet, very powerful!I appreciate the flow/ volt control. No more having to get down on the floor to adjust an in-line flow ball valve!Only reason I did not give it 5 stars.... I cannot get the pause flow feature to work. Remote acknowledges me pushing the button, but flow the continues.All in all… I would recommend it. So much soo… will be replacing both a magdrive 700 and 500 upon their going up. Both are also 20 plus, but are of much better quality than what’s being offered new today!

Very quiet pump. Powerful to. I had to lower the pressure to a 15.. it's been a week. Still pumping. Works really good. Thank you.

**WARNING THIS REVIEW MAY ONLY APPLY AS A DEFECT TO THE PUMP I RECEIVED** Great pump, unfortunately I am not sure if this is a defect for the one I received but after using it in my 75 gallon reef system with a 29 gallon sump for less than a year it was the cause of my whole tank dying. The cause was from contamination of rust developing on the propeller.I am lost for words, since I am sure all hobbyist must know how much time and money I've spent in the first year of establishing my reef tank. I couldn't figure out what the problem was till it was too late. And only after breaking the entire tank and equipment down for cleaning to set up again, I finally realized the cause of my tank to die was toxic from rust on the propeller and housing of the pump.I will say this though, a great pump and like previously stated I do not know if this incident was a defect from the pump I received or if this pump shouldn't be used on saltwater systems.So sad, since I love hygger products.

This unit is twice as quite as my older pump. bought this as a replacement for my 10 year old sump pump. very quite and powerful, really gets the system circulated.

I have this being used in my DIY cold plunge set up. It’s been running non stop for a few months and no issues. I like the remote it has so that I can change the number of gallons it pumps. It is pretty quiet too. Almost no noise coming from it.
