The ISTA Intense Flow CO2 Bubble Counter

A bubble counter is how planted-tank keepers actually see their CO2 going in, and the ISTA Intense Flow unit gives you a clear, visible count of bubbles per second as gas passes through the water-filled chamber. We treat it as a core CO2 component: pairing the bubble rate you set here with the colour of your drop checker is the practical way to tune injection for healthy plant growth without gassing your fish.

For local hobbyists, a counter takes the mystery out of dosing in our warm tanks, where CO2 behaviour shifts across the day and a steady, repeatable reading helps you stay consistent. Fill it with distilled water or proper counter fluid rather than tank water, keep it mounted upright so bubbles read cleanly, and check it periodically since evaporation slowly lowers the fluid level over weeks.

Always run a check valve downstream so water cannot siphon back during a power cut. Browse the full CO2 systems range, and read our bubble counter guide, drop checker guide, and planted CO2 guide.
