Fish Tank Filter for 100-200 Gallon, Small Pond Filter 420GPH, 4 in 1 Large Aquarium Filter and Powerful Water Pump, Fish Tank Pond Oxygen Supply and Wave Maker

I’m using this in a bathtub aquarium on my porch! Probably 50 gallons of water. After three weeks, the water is still crystal clear. Would buy again.

Great filter sadly it's way too strong for my micro fish. But it be great for something bigger and faster like comment goldfish ..or similar

couple of the pumps missing airlube regulators ......... missing 2 of 3.otherwise excellent pumps

I personally love it, but the suction is too strong. Like it sucked my turtle to it. I had to put some decorations in front of it to prevent it from happening again. Thought it would stop from functioning properly. But it didn’t. My tank is 100% spotless!! No spec of poop is safe from this filter 😂.

Very satisfied with filter.

Earl, the turtle loves his heat. Awesome that tempture is adjustable.

Mystified by the reviews, unless the product has changed. This was the most cheaply-made submersible filter I’ve ever seen. Just trying to attach the suction cups resulted in the top portion disconnecting repeatedly. Trying to get it in the tank was comical. It also hasNo adjustment for turning the flow up or down. Returning.

I'm honestly not sure if this product is broken or if I put it together wrong because the instructions are missing.I assembled it in the way it fit together and using a picture from the Amazon page. I submerged it, and then plugged it in. Nothing happened. No water moved, no sound, nothing.Company doesn't seem to have a website or anything so I don't know where to get instructions on troubleshooting it.
