  • Good Pump for Hydroponic Tower
Size: 300GPH
I am using this pump for my hydroponic tower and so far it has worked really well. The tower with the bucket is about 5'6" and the pump is able to handle that hight with a good flow rate. The size of the pump is nice and small which fits into the 5 gallon bucket I am using for the base. For something under $30 it is a good pump and does what I need it to do. I will be getting another one when I build another tower. ... show more

  • Great pump for outdoor fountains
Size: 300GPH
This pump is great. I’ve had it installed in a pretty large 3-tier outdoor fountain for almost 5 years. It’s been perfect through times when the water runs dry. And turns right back on after being out all winter when I plug it back in for spring/summer. I don’t have filter bag around it or anything.

  • Excellent pump!
Size: 300GPH
I’m so excited that this pump works in our beautiful outdoor fountain. It pumps even better than the one we had to replace. Great product and great price!

  • Plugged it in our fountain and it works great.
Size: 300GPH
So far this is a great little pump. Absolutely quiet. The flow is as expected. If it lasts, I'm very happy with this purchase.

  • Good power, quiet and filters at a good rate
Size: 300GPH
So far, this pump has been great. Love that it had 3 different attachments for my fountain attachments. Others came with only 2 and the 3rd one worked perfectly. Power seems to be really good and it’s pretty quiet. Very happy with this purchase.

  • NOT adjustable
Size: 530GPH
Pretty disappointing. Product comes with zero instructions, and includes a plastic cowling piece that fits nowhere on the pump. But the biggest disappointment is the flow control knob, which does NOTHING when you turn it; so the flow is full-on no matter what. I bought this so I could dial in the right flow for my fountain. It'll be going back to Amazon tomorrow. ... show more

  • Good but not quiet
Size: 300GPH
Works well, but hums and that is bothersome. Going to buy something quieter, if I can.
