Seachem Glass CO2 Beetle Diffuser 27mm

The diffuser disc is impressively large and breaks the CO2 into a fine mist that disperses perfectly across my 90-gallon tank. I love how the clean glass design lets me see exactly when the bubbles start flowing.

Took a while to dial in the bubble count, but once it settled the CO2 mist spread beautifully across my 90cm tank. The large disc surface makes a noticeable difference in how evenly the gas dissolves compared to smaller diffusers I've tried.

The diffuser disc covers a ton of surface area, so my pressurized setup is saturating the water much more evenly than the old ceramic stone. I can actually see the fine mist spreading across the whole tank now. It feels delicate but has held up perfectly for three weeks of daily use.
