I've got my CO2 tank and regulator under my tank, my bubble counter is on top of my canopy, but after a while at night the bubble counter completely fills with water. I have a check valve between the cylinder and the bubble counter to make sure water doesn't go down to the regulator, but should I have another check valve to keep water out of the bubble counter? (luckily I'm using water and not mineral oil or anything so I just set the counter on it's side for a few moments and drain it back into the tank via the airline).

What am I doing wrong here?

Adding a check valve between the bubble counter and diffuser will keep water from going into the BC and protect your regulator. I have a check valve before an after my BC , I have mineral oil in my BC since last xmas and never had to add any IMO it makes it easier for me to see the bubbles.
