bubble counter liquid evaporation

Recommended Posts

I have a ista c02 pro with dual guage regulator, solenoid and bubble counter running into a ista reactor. Everything seems to be working Ok except the water in the bubble counter is evaporating. Is this normal, I have refilled twice in two weeks. Drops were 1bps.

It is on a timer, and I noticed there is water in the c02 line when it shuts off, so I'm not sure if that is normal either.

Help or suggestions welcome

Water evaporates into the CO2 as it passes through. You will have to continually top up the water or use a fluid that doesn't evaporate as fast like mineral oil or glycerine. (Both fairly harmless to you & fish). These liquids are more viscous though so you will get a different bubble count compared to water. The actual bubble count itself doesn't really matter as long as it is consistent, so you know how much CO2 gas is getting used.
