Review: Nice and quiet - I have this installed in a sump for my discus tank. Works well and runs quiet. I did notice that if you reduce the speed, it gets quite a bit louder though. If I could do it again, I’d buy a smaller one and then max out the controller to reduce the noise. But I’m very satisfied.
Review: Good value - It was easy to plumb into my system and has worked flawlessly for the last week or so. The controller works well and the feeding pause option is nice. At max 1000gph it is quiet. If you plan on only running at max it's pretty low noise but as you dial it down the noise goes up, seems like lower should be quieter but it's not. For a DC return pump it seems to be good value.

## Features

### ⭐⭐⭐ Strong pump but noisy
*by J***. on January 8, 2025*

it’s a very strong pump for its size but i don’t use it any more since it’s super noisy with a wrattle inside i don’t know if it’s broken or that’s just how it is
