Colombo Glass CO2 Diffuser 40cm

The 40cm length on this diffuser is perfect for reaching deep into my planted tank without extra tubing. The glass feels thick and well-made, and the fine bubbles spread evenly across the water. My plants are pearling like crazy just a week after installing it.

I’ve been using this diffuser for a month now, and the 40 cm length makes it easy to position in my tank without ugly tubing. The glass feels sturdy, and the fine bubbles are consistent.

Finally the bubbles are fine and consistent, not those big chunky ones that just float straight up. The 40cm length made it easy to tuck the diffuser behind my driftwood without it being an eyesore. My plants are pearling like crazy now.
