Flexzion Powerhead for Aquarium 2200GPH Submersible and Adjustable Wavemaker Water Circulation Pump, 360 Degree Oscillating Mini Aquarium Blower for Coral, Reef, Fresh or Saltwater Fish Tank Pump

I didn't know if it would be strong enough to create water movement across a 6' 120 gallon tank. It does. It is to soon to rate its longevity. I purchased the magnetic mounted version and the magnet is easily strong enough that I don't worry about it falling down into the sand which would be a grand mess.......I said Sand Which and now I'm hungry.

Don't buy this pump . I had two in two weeks and both impellars disintegrated . Wouldn't recommend it at all !!!

Great product. Adds a lot of water movement. Nice magnetic feature vs the suction cup.

Very powerful works great the magnet isn’t the best though

Impeller stopped spinning, motor burned out within weeks.

Junk! Didn’t last two months before it locked up! Disassembled it to clean and still nothing. Waste of money, in the trash it went.

works great!

Quit working after 1 month.
