hygger Aquarium Bubble Strip, Nano Air Bubble Curtain Wall Aquarium Air Stone Kit, Quiet High Dissolved Oxygen Diffuser Fish Tank Bubbler Decorations for Freshwater Saltwater (13.8 Inch)

Solid, sturdy, heavy enough to stay where it's put in the aquarium, and produces a nice bubble wall. I'm using this in our 55 gallon with a new hygger dual adjustable pump (it came with two small ball airstones) and a new hygger disk air stone. Picture of tank shows all four installed. (And one of two very old clown loaches.) All three items are definitely worth the purchase, best I've found so far.

Works great lots of bubbles. Much better then those small air stones. I have other Hygger products and they're all good quality items.

Great for smaller aquatic animals and ever their young. Bubbles are incredibly fine. Took about an hr before the bubbles really started to pump out throughout the entire air strip, so you might have to give it a little bit of time to get going.

Ça fonctionne comme je l’espérais! :) je suis satisfaite

Great
