Ista Intense Flow CO2 Bubble Counter

The bubble counter sits right in the line of sight so I can actually read the count without squinting, which matters when you're dosing a densely planted tank. It handles the higher CO2 volume my setup needs without the water creeping up the tube, and the chamber clears fast after a water change.

Finally getting consistent bubble counts on my heavily planted 65-gallon, and the larger chamber makes it easy to see even at a glance. The flow-through design really does keep the bubbles moving without getting stuck.

Swapped this onto my 75-gallon and the wider body handles the higher bubble rate my plants need without the counter fogging up. The bubbles stay distinct even when I'm pushing a lot of CO2, so dialing in the count is actually quick now.
