Review on Hygger Quietest Aquarium Adjustable Powerful by James Thelin

This pump is amazing, it can do it all! Very powerful, I semi lowered it by hooking it up to a 4 way air trap to 4 separate air discs in my 150 gallon fresh water tank. If I lift it higher, the bubbles get too strong, the thing has incredible air power. I replaced my Fluval Q2 with a few other pumps as it was getting noisy and stopped producing strong bubbles. I tried the Tetra Whisper AP150 and it worked well, but without the adjustment knob it was still louder than I would have liked. Then I bought an Eheim 400 with two adjustable air outlets and it wasn't bad, but it was still louder than I would have liked. This Hygger pump blows other pumps away, it is extremely powerful and very quiet. My aquarium is very large with 4 year old cichlids and huge 14 inch catfish and this pump has more than enough power to fill the tank with endless bubbles. Spit on the buzz.
