Seachem Glass Bubble Counter

A glass CO2 bubble counter that sits in the CO2 line so you can see and set the injection rate, the simplest way to dial in bubbles per second on a planted tank.

Key features

• Clear glass shows every bubble
• Lets you set a repeatable CO2 rate
• Fits inline on standard CO2 tubing

Fill with water to the mark and read the bubbles; pair it with a check valve so water cannot back up into the regulator. More plant fertilizers and additives. Available for local pickup at our Lethbridge store.
