kimi san,
try this
CO2 tank------->NRV------bubble counter------->NRV----->tank
if i put NRV after bubble counter (BC), how water gonna fill in the BC???

kimi : i got same problem too. but as i think its normal becoz the water will dissipate after some time of use. its becoz the bubbles make splashes when it burst at the water surface inside the bubble counter. thus, the gas carries the evaporated water to the aquarium (not the co2 tank).
the trouble is that we need to refill the water once in a blue moon.
i kept mine going 24/7 on manual regulator, no on-off solenoid la...
*also, if ur tube is clear/transparent type, if there's water inside the tube from co2 tank to the bubble counter, then ur check valve got problem lo.... if there's water droplets after bubble counter but before the aquarium, i think its normal.
hope above helps. other sifus may chip in if i'm incorrect.

how to refill the BC??
later will check the tube after tank, before NRV.. hopefully, no water backflow to co2 tank....
