Seachem Glass CO2 Bubble Counter

Seachem Glass CO2 Bubble Counter

The Seachem Glass Bubble Counter is a standalone in-line bubble counting device that mounts on your CO2 line between the regulator and diffuser. Fill the lower chamber with water; CO2 bubbles rise through the water column one by one, giving you an accurate visual count of your bubble rate per second. Monitoring bubble rate is the easiest way to verify consistent CO2 delivery without a drop checker and lets you quickly identify when your regulator needs adjustment, your cylinder is running low, or your airline has a leak. Constructed from borosilicate glass for a clean, natural look that complements planted aquarium setups.
