Review on KEDSUM Submersible Fountain Aquarium Hydroponics Fish & Aquatic Pets and Aquarium Pumps & Filters by Courtney Stone

Great little submersible pump. I use it to change the water in my aquarium. NO MORE BUCKETS. The flow rate suffers a little when pumping water 4 feet up, but it gets the job done. When I fill up my 20 gallons I can do other tasks like cleaning the filter or planting crop residue and transplanting the crops. Overall I am satisfied with this product. When it's on, it's pretty quiet. I only hear a low hum. Another plus is the adjustable flow rate. You can use this for a small waterfall in a pond or maybe a small fountain. UPDATE: The flow rate adjustment knob only stopped working after a few uses. Really disappointing but it still works. Now it's in full swing. I don't mind, but if this setup is needed it will be a problem. Tip: Do not touch the adjustment knob with your hand. 1 star deduction for that.
