MTS Aquatics - Refillable Bubble Counter

Take the guesswork out of CO2 dosing with our aquarium bubble counter, that's also refillable while installed! Mainly for use in planted tank setups, this easy-to-use device allows you to visually monitor the exact rate of CO2 being delivered to your tank - bubble by bubble.
 
Simply fill the chamber with water, (RO preferably), connect it inline with your CO2 tubing, and watch the bubbles pass through. Using Bubbles Per Second, (or BPS), calculations gives you a reliable, consistent way to fine-tune your CO2 levels for lush, thriving plant growth.
