Difusor de ar flexível Superfish

Finally, a way to get a gentle stream of bubbles exactly where I want them behind the driftwood without a bulky stone. The material is flexible enough to snake around corners and stay put, and it doesn't seem to collect grime like my old ceramic diffuser.

Bent one into a tight U-shape behind a rock and it stays put perfectly, no kinking or blocking the airflow. The bubbles are much finer than I expected from a flexible tube, which is a nice surprise. My corydoras seem to enjoy swimming through the curtain it creates.

I tucked this behind a piece of driftwood and the bubbles come out in such a nice, even curtain. The plastic is stiff enough to hold its shape but easy to bend exactly where I needed it.
