hygger 400 GPH Quick Water Change Aquarium Pump Submersible Fountain Water Pump Fish Tank Pond Drain Transfer Pump with 2 Adaptors

Paired with a 25ft hose with 1/2” ID, drains easily without being concerned about the flow being too strong. I have river rock as my substrate and it got half of the funk stock at the bottom. If you’re changing water often enough, this should serve you well.However when I went to fill my 55 gallon tank, setting bucket on floor presented some challenges. Quick fix I put the bucket on top of a step ladder and we were running again. Flow was perfect, didn’t impact substrate on re-entry.

At first I was not sure if this would work and I felt hesitant to even put it in water even though its submersible but I actually did manage to find a hose from another product I bought from amazon that was trash for water cleaning and it fit on the fittings that come with this product. The hygger 400 comes with three fittings and I was impressed that this actually worked out, anyway the machine isnt very quiet which is fine but it does a stupendous job!! It not only absorbs the water but it did not disturb my substrate so cleaning was much much easier. I was able to get the entire job done in 2 hours. (Probably could have been sooner but I was fiddling with decor)So in a nut shell:Worth the money? YesSaves time in weekly water changes? YesDisturbs decor and substrate? NoEasy to use? YesComes with a hose? No.Comes with instructions? Yes.Can be safely submerged? Yes.I have two goldfish named Twin Flames and they reside in a 21 gallon tank.

I use these for water changes. My only struggle is when plants or sand get stuck in the intake. They have okay power for what I do and are a good bargain.

No more buckets, no more bathroom trips with buckets, no more turtles messaging with the tubes. This is AMAZING !!! Took me literally 5 mins with my 20 gal tank and maybe a good 15 with my 50 gal tank ( I got the cheapest and smallest size)I am getting another one for reserves lol. I absolutely love this ! It draw everything in, gets all the water except maybe an half inch at the bottle.GAME CHANGER

Was good while it worked. Only got to use it 3 times until the unit stopped working 2 weeks after my allotted return period. So now I am stuck with a pump that won't power on. Worked great for water changes on my small aquarium until the last time I tried using it and it was dead.

The best pump I have ever bought. Very durable!

Why did you pick this product vs others?:For removing water from a 150 gallon tank and from an above ground pool. Great pump worth the purchase.

It worked a few times now its died and wont turn back on. It was quiet but not nearly as powerful as they say. Sadly I wont be buying another. Not worth the money when I have a 7 year old aquatop pump that hasn't had an issue since day one. I only used this to do water changes from my brute trash can never touched substrate so I know its not that. I'm sad because I like the brand but I guess not everything they make can be as amazing as their lights.
