  • great product, even better service!
Style: 370 GPH
bought one of these for a hydro garden project - worked great out of the box, easy setup, great flow as advertised! Had an issue after a few weeks of service, took it apart and the impeller had failed and broken ( appeared to be a manufacture defect in the impeller not an actual fault in the overall pump or design. Filled out a support ticket and not only a fast response, but a solution to my issue was shipped out and arrived in days! thanks so much Hydrofarm for standing behind your product. Ordered another pump as a back/ready for my next project! ... show more

  • So far, so good
Style: 370 GPH
I'm using this in a diy aeroponics set up. It's been running 24/7 for 30 days and is running at a consistent rate. The noise level is not annoying, however, I keep the door shut to the room the unit is in. (Cats don't eat lettuce, but sure enjoy shredding it. 😳) I'm also using the overpriced filter bag as an added level of protection should there be any stray solid matter in the water. ... show more

  • 400 gph pump
Style: 370 GPH
I bought this pump for in line use home made aquarium gravel vacuum. At first it stopped working, found the impeller bushing was jammed. Easy fix, however, I should have brought the 550 gph model. Seems there isn't enough power for my needs. Otherwise it seems well built but have to question the water flow rating. I would recommend going with the next higher rated pump and installing a ball valve in order to adjust water flow if needed. I can't comment on longevity due to my short term use. ... show more

  • Pumping upwards 4ft - no problems
Style: 370 GPH
I have been very pleased with this lump for my tower garden. It pushes water straight up about 4 ft with no issues and I believe it could go much higher if needed. It is not super quiet, as it has a vibration to it, but that is not an issue for me as this is located away from a common area anyway. Good product at a good price!! I would recommend this. ... show more

  • Broke after 6 months
Style: 370 GPH
Pro: Cheaper on amazon then at the store Has a variable nozzle to change the water flow rate Seems good quality Con: No on or off button Variable dial is on the unit so you have to pull it from the water to change it Not the strongest Overall: I bought this to put into my 5 gallon bucket home made cloning system. It works well so far and has been running non stop since 2 days after coming in. As long as it remained fully submerged it works well, I sometimes let it go a little low and the pressure starts to drop but that is rectified when I ass more water. I will update if anything happens over time Update: after 6 months the thing broke. Sadly I missed the warranty time because I didn't use it right away 6 months of use and it does, not worth it. ... show more

  • Noisy!
Style: 370 GPH
I bought 2 of these to use in low pressure aeroponics systems and they are both extremely noisy. They seem to work fine, but they sound like they're about to burn out. They sound that way even when they're pumping pure distilled water. I checked them and all fittings are tight, and everything is perfectly clean. I hate to have to replace them, but I'm just waiting for the day they fail. ... show more
