Green Aqua Bubble Counter Fluid - 30 ml.

Refilling water that evaporated or just got pushed out of the CO2 bubble counters can be an inconvenience. This high viscosity, non toxic fluid is a perfect alternative to water. It is a transparent hygroscopic solution with no smell. High E422 content ensures that it will not damage the solenoid valve in case the check valve has a malfunction. It is also harmless to fish and shrimp. Use:  Do not dilute. Slowly fill the bubble counter with a syringe to about three-quarters. Wipe the occasional drops off the exterior. Amount : 30 ml. (approx. 2-3 fills)
