hygger 215 GPH Quick Water Change Aquarium Pump Submersible Fountain Water Pump Fish Tank Pond Drain Transfer Pump with 2 Adaptors

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.

Exceptional product, perfect for my application. This product is well made and pumps as expected. A little bigger than expected, but not a problem for my application.

I’ve got this in the ATO of my reef tank. I’ve used pumps with stainless steel screws before but I will be monitoring them every refill just to make sure there is no rust. So far it’s been a few weeks and no signs.

I've only used it once, and let me tell you. I did a 25% water change, start to finsh, in my 29 gallon aquarium, in less than 10 minutes! BIG back AND time saver! I tried the model a step below this one (~150gph?) Which worked OK but it was too slow for me and I have a tall tank so it struggled to pump the water up to where I needed it. So i tried a different brand at 800gph... WAYYYY to much. But this 400gph model is just write! And seems to be built well. Pair with python "the hook" and some 3/4 id silicon tubing and you're set! Would highly recommend 👌

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.

This thing is awesome and fast and helps save me so much time doing water changes on my two saltwater aquariums. I also throw it in my rodi container to aerate the water the day of my water changes. It did come with some adapters for tubing which was nice but I do wish it came with actual tubing though.

Our use-case is: We have a 40gal fancy goldfish tank and we age the water in a companion tank (no livestock, just water + conditioner and a bubbler) for a few days between changes. We use a facet-based water changer (Google "Python water changer" for the idea, but we use aqueon w/ aftermarket 50ft tube after having issues with the green-plastic python design) to drain the water, but then we had a normal water pump to move it from the aging tank back into the GF tank.Whenever we'd get down to the last 2-3 gallons in the aging tank, our old one would need to be laid down, and maybe held in place and it couldn't even get the last 0.5 gallons anyway. What a pain. This one sucks from the bottom and can empty about 99.5% of the water out of our little 10 gallon water ager. I haven't had a need yet since we downsized our tanks (I had 10 at one point before moving), but I can think of many uses for a pump like this. I believe any intermediate+ fish keeper absolutely should keep this on hand even if they're not using it regularly. Emptying out a tank for a move or for a super-clean would have been SO much easier with this rather than trying to use my waterchanger and a turkey baster to get the last .5gal of water out of my tanks.If you need to fully dry a tank, run this until it is making so much noise you're worried, then tip the tank onto a slope so the water pools and pump out what you can, then lay a towel down for 10-30m and finally towel up the rest. That's maybe 5-10 mins of labor and the rest is monitoring. Highly recommended! Note, however, that the flowrate isn't high, so if you're on a tight timeline, you may want to upgrade to a higher GPH for 50, 75, 100+ tanks.

*** Edit Jan 2021 - Due to my previous review the customer service team reached out to me and in doing so made quick work of sending out a replacement pump. A faulty item can happen anywhere and it is great that they took the initiative to make things right. I have not been using this new pump for very long due to just receiving it but due to their customer service alone they are getting three stars for now. I intend to update this review again in a few months to reflect the reliability of the new unit.So I got this for a sump filter for my 75gal turtle tank. It worked good for a short bit louder then I wouldve liked but there was good pressure. On one of my maintenance cleaning of the filter I noticed the case was cracked which was weird since I never dropped it so I patched it with some silicone thinking thats why it had got louder which made no difference then one night trying to go to bed I hear this awful noise so I run over thinking it was low on water level which it wasn't so I quickly unplugged it for the night. Next morning pull it out try cleaning it and when I pulled the propeller out there were chunks of plastic or something so I just threw it in the garbage and ordered an actual aquarium sump pump which I should've done from the start.
