Review on Fluval 88G CO2 Bubble Counter Ounces by Jacqueline Mclaurin

When received it worked as expected. I just used deionized water in the chamber to see the bubbles and it worked fine. It can be a bit odd to hang elegantly because it's such a lightweight device with heavy hoses dangling from it. The connection between the suction cup attempts to stop rotation, but the rubber suction cup itself allows for lateral play. I ended up hiding mine as it was ugly and off center. The reason it only gets three stars is because after about 6 months of installation I removed the tube from it (after unscrewing the mounting nut) and the entire stem broke. . It has since been thrown in the trash.
