hygger 800GPH Quiet Submersible and External 24V Water Pump, with Controller (30%-100% Settings), Powerful Return Pump for Fish Tanks, Aquariums, Ponds, Fountains, Sump, Hydroponics (25W, 9.8ft)

Had an old Pondmaster 1000 submersible filter with 3/4" hose and needed a pump on it for a new 125-gallon indoor aquarium setup. Ran the 3/4" hose to the intake using the 3/4" soft tube connector (included), then put the 1" rigid pipe connector (included) on top to connect an outflow pipe to. Went to Lowe's and bought 1" PVC pipe and 45 degree elbow (do direct water up and away, across the tank from the end the filter is at, to get good flow). The 1" pipe and elbow were too big; took the 1" rigid pipe connector and figured out smaller PVC pipe and elbow (I think I got 3/4") were needed, and fit so snugly I haven't needed PVC cement (a can would've cost close to $8). Already have a saw to cut the PVC pipe. I adjusted it to the lowest flow setting, which looks vigorous enough but not too powerful.Very impressed with how quiet this pump is. The setup's in the living room, so noise matters, and so far, really happy. I put a row of bio media under the coarse filtration pad that came in the Pondmaster 1000 filter, so coupled with strong flow from this pump, that would do well. It's a turtle tank, so the water level is several inches from the top; hang-on-back filters like the AquaClear I feared could loose their prime in a blackout, and canister filters are a pain to take out, disassemble, clean and get primed again (I've used a few different models). This appears simple, easy and powerful. The pump has a button you can hit to stop flow 10 minutes while you feed fish, and the control panel hangs outside the tank.

I ran a pond master 5 in my f.w planted tank with sump and old reef bioballs.Pond master was loud vibrating drove me crazy.I got this pump the 33. Its pushing plenty water at 4.7 ft. And its not cranked up to 100% about 70% i drilled a 3/16 hole in the hood for pulling water from bottom of sump put a section of ridged air line pipe connected my CO2 onto that pipe that eliminated a co2 bubbler and the impeller makes a million micro bubbles and one less item to deal with. If it holds up most quiet pump ive ever owned and I've use iwaki little giants Rio some I cant recall.After 65 yes in hobby and owning a local fist shop I've used them all I think ?

Setup: 800GPH model | Submerged in sump | Using 1' barb & flex tubing.I recently had one of my Sicce syncra 3.0 pumps go out on me. It was not that old & despite routine maintenance, it began to really struggle. I decided I would try another brand & stumbled across this one. With my second Sicce still hooked up (for now!), I can really notice right off the bat just how silent this pump really is. The vibration level is hardly noticeable. I had to feel the flow to make sure it was running. The Sicce pumps no matter the setup (rubber legs, on foam, off walls, etc.), give off this buzz sound that you eventually get used too....The flow itself is as advertised. The setup was simple.This pump is truly impressive so far. I will create an update post if anything fails or any issues occur sooner than anticipated!Update: 3/16/2021 - the pump is still running like a champ! So much so that I purchased 2 more (1 to replace my other sicce & the other to go on a custom river tank). These things are still silent. Very VERY impressed with hygger on this one! Highly recommend.Update:7/22/22 - all 3 pumps still running! Not a single issue. Still shocked!

1st - I was hoping to go inline, the unit says it can, then says to tighten and glue, seeing how it was assembled, if you do all that and the o-ring fails (age/pressure etc.) you'll still have a puddle.2nd - very compact design, moderate power, fit easily in my sump box, was the easiest pump replacement for a sump return unit I have ever had, the bottom feed intake, made it easier to refill my tank after working on the sump.3rd - this is for a 55 gal, fresh water plant and quarantine tank. water output through 3/4 inch pvc about 6 feet of travel, unpressurized return is adequate, I am running at 85% or 30watts. the difference with the Iwaki clone (20+ yrs & 3 aquariums) is pretty vast, both on output and fuel use (way less for both). it is far quieter than the old pump.4th - for me this was a good economical choice, fits the tank and its need, I doubt it would do as well for a similar size salt water set-up. Also being in sump, not inline, it would take space that skimmers and other salt water gear needed, now for a small refugarium it might do the task.I would buy again, probably higher output, not lower.

Great pump. The ability to dial it up or down is a great feature should you change the design of the water feature or add a bigger waterfall

There is no way to connect 1 inch flexible hose connector to the pump. The 1 inch rigid connector is ok but the 1 inch flexible connector base is smaller than the rigid one and for that reason it just slips out of screw connector.

Had the pump a week now so can’t comment on how long it might last but the construction of this pump seems pretty heavy duty so it looks very promising it will last a long time and I absolutely love it so far. It’s just what I needed for my refugium sump, I haven’t heard the pump make one noise yet, this thing is quiet. Highly recommend this product, just be careful if your putting this in a tight spot because their measurement for the width of 3.1 is inaccurate I had a space that this needed to go in that was just bigger then 3.1 but definitely enough bigger and this did not fit. I had to squeeze the pump in the return section which I had to bend my plexiglass divider so it would fit down in the return section. So my recommendation is if you have a 1/4 inch more then the 3.1 they state your good . If it is gonna be close in size do not buy.
