Colombo Glass CO2 Diffuser 25cm

Put this one next to my drop checker and the CO2 bubbles are noticeably more even than with my old ceramic disc. It's long enough to reach the perfect spot in the tank without extra tubing. The glass is crystal clear, making it nearly invisible once installed.

The glass feels really solid and the 25cm length lets me position it exactly where the current carries the bubbles. Within a day my drop checker turned a steady green and the mist is so fine it looks like a soft haze across the tank.

The slim 25cm design fits perfectly in my 60cm tank without sticking out awkwardly, and the fine glass construction makes bubble distribution so even my plants are pearling within days.
