Aquarium Filter for 55-150 Gal. Tank Crystal 300GPH Biochemical Filtration Powerful Pump Submersible Internal Fish Tank Filters Large Tank Pond Clear Wavemaker Air Supply 4 in 1

Great pump i used it along with aquarium scrubber glassing fabric to keep my homemade icebath clean. I would unplug when entering for safety and it saw quite a bit of use and abuse. I accidentally left it out side before i moved recently and it got full of bugs so i trashed it but will buy another.

Not Working - Used Product

Ive had it for over a year now, i use it with my canister filter and my tanks water stays within perfect range. The extra biofilter helps keep the nitrogen cycle consistent, even if we do a large water change. Gteat value. The only thing i don't like about it is that my Oscar still isnt used to the fast moving water, but without it in the tank she was starting to develop hole in head. It's pretty much in remission and she's healthy enough to fight the filter at night.

This thing is a powerhouse. It gets the job DONE. Taking it apart to service it is incredibly easy, too. Yes, it's a bit loud but with how much water it moves that's not surprising. And at this price I think it's well worth it, it's an absolute beast!!

This is the best filter I’ve ever owned. I have a 75 gallon fish tank that had been without a filter for a couple of months; I put this filter in and when I woke up the next morning the fish tank looked 70% better. By night, 24 hours, my tank was crystal clear and the fishes had the zoomies! The water flow is pretty high even when adjusted on low but it’s a solid 10/10 and the best part is that you don’t hear it running. I’ve owned quite a few fish tank filters and this one beats the others in price, quality, and maintenance! Highly recommend.
