Pros & Cons
Cons
Pennplax is defective. Seller agrees to refund without hassle.
This giant contraption only emits big bubbles from about 8-10 locations. It bubbles out of one spot over 12 length. Sadly, the bubbles are so strong at the proximal end and not much at other places as seen in the clip.
The stone only produces bubbles 2 inches from air inlet! Can not recommend this air stone. It is not a true stone that emits a froth of bubbles from hundreds of locations. Initially the air simply finds the easiest path out of the rock.
Not dispersed across the bar. On the bar, the air only comes out in one spot.
Highlights
Quality
Great bubbler for the price works just as it should
The air stone is great quality for the price
Competitiveness
Much less expensive than purchasing a “pond” airstone
I have mine buried under a couple inches of coarse sand and powered by a hygger 5w adjustable air pump set rather low
This airstone stays where you place it

Considering how cheap it was i was expecting something small but the stone is actually very long

The bubbles only went out the first half of the stone but i’m pretty sure that another air tube can be attached on the other side to make it even

You have to cover them with aquarium gravel so the air can make it through the whole stone
