Review on 🐠 NO.17 Submersible Aquarium Internal Filter Pump, Adjustable Fish Tank Filter with Water Pump for Optimal Water Filtration in Fish Tank by Tiffany Williams

I bought this pump to create micro bubbles that help me lift all the waste and dirt up and into the overflow. It's compact and works well for my application. I only use this pump for in-tank service, it doesn't run 24/7. I like that the intake is covered with sponge filters to keep any fish or creatures out of the engine. The device is quite slim and small. Less than expected, but that doesn't bother me. Overall this is a good pump for moving water and adding air to the stream. It's like a power head with the added benefits of a filter.
