Review on 🐠 Aquarium Fountain Submersible Water Pump: 160-1188GPH for Fish Tank, Pond, Garden System - Ultra Quiet, Adjustable with 3 Nozzles by Tim Olson

I put it in a 25 gallon tank Yes I know 400 gph sounds like a lot for a 25 gallon tank! Well this pump is very special, it has a flow regulator on the side that shuts off the flow completely at least 80% which works for me because I'm going to need a high flow pump next month or so as my plants get fatter . This is the perfect pump for me because I can very easily change the flow whenever I want, it comes with suction cups as well as four tiny rubber tips (don't know what to call them) which I prefer to the suction cup! Also I can't hear it which is amazing and my betta is swimming normally, the water is pretty calm, the valve is fully closed only letting about 20% of the water through! The only thing I didn't like was that the exhaust nozzle is quite small and the included nozzles don't really add to its size. To fix this I used a bundle of teflon tape and wrapped the exhaust nozzle around to fit the 1" pipe hole I had and it works great!
