Review on Fluval 88G CO2 Bubble Counter Ounces by Carmen Polk

This bubble counter is perfect for the Fluval Mini Pressurized 20g-CO2 Kit - 0.7oz available here at Revain. I'm not sure how well it will work with really high pressure systems for large tanks, but mine is rated for a 20 gallon/medium sized planted tank. in a tank I filmed for about 50. I ended up sucking him off the side of the tank. Even when filled with water, it's pretty light. I used distilled water to fill the tube (with a very small amount of blue food coloring for aesthetics). I also taped the threads to minimize the possibility of CO2 leakage. In general very satisfied. No complaints and very helpful.
