Seachem Bubble Counter - 6 mm

The Seachem Bubble Counter is designed to monitor the rate of CO2 injections in planted aquariums of all sizes. The sleek and slender glass device is placed in the CO2 gas line and helps to minimize the visibility of unsightly and visually distracting CO2 equipment in the tank. Allows aquarists to quickly and easily check CO2 output whenever they want. Compatible with 6 mm (1/4") standard airline tubing.

Instructions:

To attach tubing to glassware, wet the inside of the tubing with water at the attachment point and carefully slide tubing over glass. The use of other lubricants is not advisable as these usually make the tubing slide off of the glassware too easily. To avoid breakage when removing tubing, do not pull tubing off of glassware. Instead, cut tubing carefully along the attachment length to release the glassware.
