Review on 🐠 Eheim PHL207184, 4.00 x 6.00 x 4.00, Black: Superior Quality Aquarium Accessory by Andy Sayloon

I have had this air pump for 2 months now and it works great and is still QUIET. I use it in a 20 gallon tank with 1 bubble wall, 1 rock and both bubblers that come with the pump. I believe it's powerful enough to fire another tank since both dials are in their lowest position. I was able to hang it on a hook next to the tank because it's so QUIET - I didn't have to hide it in the closet wrapped in towels to muffle the noise. I am very happy with this purchase! I have been in the aquarium business for 30 years and this is the best air pump I have ever used. I have used other EHEIM aquarium products and have always been satisfied with their performance and finish. I rely heavily on other people's reviews when shopping at Revain and hope this helps someone in their decision.
