HydrofarmAAPW550 33-Watt 550 GPH Indoor/Outdoor Hydroponic Aquarium Pond 6ft Power Cord for 55 Gallon Reservoirs Submersible Water Pump, 550-GPH, 8.4 x 3.4 x 6.4 inches, Black

Active Aqua Submersible Water Pump, 800 GPH, for my cold plunge tub, and it works perfectly. It efficiently circulates the water, maintaining a consistent temperature, and operates almost silently, which is a huge plus.Installation was easy, and the pump feels solid and reliable. The compact design fits well in my setup without taking up much space.Overall, I highly recommend this pump for anyone with a cold plunge tub. It’s quiet, powerful, and does the job excellently.

awesome so far, quiet and pushed some water!

I bought this pump for a DIY cold plunge. It's really quite and does the job. It runs 24/7 and after a few weeks no issues.

Filter clogs frequently..small filter..pump works great..lots of power!

The media could not be loaded. We had high hopes due to being the same brand as our chiller unit for our cold plunge. This pump does not meet the standards. Using it as an inline pump, there is no stop for the adaptor. See video. So that means while setting up the hoses and running it, the adapter spun/turned off and started losing water everywhere. Also, the housing is not made well. The cheap plastic broke when tightening the top fitting down. See picture. It’s like they didn’t make any room to have the o-ring seat properly when tightened. Will be buying a different brand pump and never going with this brand ever again.

Purchased in 2018, this has been in my outdoor pond for 5 years.Only this year, five years later, has it began to slow down and make a rattling noise. It's not moving as much water as it used to.I use this for a reverse flow (up flow) biofilter with appx 24" head pumping through 15 layers of green scrub pads in a ceramic flower pot (an EXCELLENT way to hide a DIY filter, BTW)Highly recommended for a CHEAP low head / low pressure / high flow pump

I bought this pump in 2015. It ran for 9 years in my fountain. I just bought another and was happy it was still available. Prior to this pump I replaced a pump every year.

I have two of these pumps, bought in 2015 & 2017. They run the waterfall in my pond. They have been running 24/7 for 7 and 9 years. What more can I say.

Just got this today. From all of the reviews I was surprised how many questions I had about the pump.1) It's apparently recommended for 15 gallon tanks (I'm using it for a container garden which is about 90 gallonsish). From what I can see it is most definitely pumping like a beast - the water in my container would make a teeny human sea sick. - Very impressed with the power2) It comes with both of the attachments - so you get the air induction hose/muffler WITH the the two optional tube fittings you see in the image they post on the ad.3) It fits a 1/2" tube (I bought the black vinyl one that's recommended - it fits perfectly - snug)4) It seriously is ridiculously small - A bit smaller then an Iphone 4 dimension but thicker obviously.5) Both of the air valve tubes stay ABOVE water - for some reason I was very confused about how the aeration would work but the manual explains it.6) Note that the power cord is quite short. I think my hair dryer has a longer cord, but it's about 6 feet'.Since it's day 1 I'll see how it goes - we're running it with no pauses and plan to do it through a Vancouver Canada winter (mild - only a handful of days of snow a year on average) so I'll update if it dies on me. If it lasts a year I'll be happy with this price.

I use this pump to power my automated indoor garden watering system. So far the pump has proven capable of pumping 2 gallons of water per minute with a 4 foot lift and 8 separate outputs on the lowest setting.The noise level is reasonably low, on par I would say with other pumps I have seen, certainly not unpleasant.The pump comes with a large collection of fittings for differ ID tubing which was convenient, it also came with an air line attachment fitting that allows you to pump your air directly into the tubing. I didn't find this an effective feature as the air stone does a much better job of delivering air more equally.I am very impressed with its overall performance.

Pros:Magnetic Drive, therefore providing back pressure does not hurt the motor ( from what I understand )Easy to cleanPumps efficentlyCons:The venturi's that come with it are poorly build / cheap quality.Mine was missing some hose attachments.**CAUTION** The output port (the top bit) is not standard size, thus pvc attachements will not fit, only hose attachments will. I spent hours looking for pvc attachements that will fit, with no avail. The inline port does fit 3/4 inch pvc attachments tho.

Works well, quiet. I have it on a timer 15 seconds on and 5 minutes off. ran it for 3 months no problems. I'd say it is not powerful enough for a tote aeroponic system. I have a 102L tote with PVS pipes and about 16 180 degree plastic sprinklers. the pressure does not create a fine mist. I'd suggest the 800GPH.

I have only used this pump a few times to experiment with my ebb & flow hydroponics system. Will be using it often very soon, when my seedlings are ready for the system. I use this for 4 x 4"OD x 10 foot long PVC pipes and they fill up and drain perfectly with this pump. I tried only 2 PVC pipes but the pump was way too much, even on the lowest setting. I bought two thinking I would split the system. I would have to exchange for a smaller GPH pump if I stayed with the split system, so instead I will just keep the second pump as a spare. They're $20, so it doesn't hurt to have a backup.
