Review on 🐠 HITOP Single Outlet Aquarium Air Pump: Quiet Oxygen Pump with Accessories for Small Tanks up to 15 Gallons by Chris Pinkney

Just installed mine, took 3 minutes and works great. GENERAL - I have a 3.5 gallon and needed an oxygen source. I didn't know what to expect from twenty bucks, but I couldn't have asked for better. ADJUSTMENT - Comes with an extra hose for larger aquariums, I cut mine to fit exactly. Comes with a T-tip, if you want to run two bubblers, use the extra hose. Comes with a check valve, but there is no point in simply placing the pump over the aquarium. Anyway, the airflow is better. If you don't like the way it looks, just grab a plastic bar and some suction cups to keep it off the back of the aquarium and out of sight. Just make sure it's still above the water level if you're not using a check valve. I will, I will add new photos soon. NOISE LEVEL - Super quiet, no "hum" at all, even on the plastic cover, there are silicone caps on the "legs" of the pump to prevent this. It's barely a buzz. It just blends in with the hum of the filter. SIZE - I like that it's small, easy to hide, not bulky and doesn't get in the way at all.
