Need to refill bubble counter after 1 month?

When I set this GLA system up a month ago, I tried to gather as much info about how to set it up as possible. When it came to the bubble counter, I had read that some were using mineral oil or other liquids besides water. Since it was my first time, I decided to go straight RO.

It has been just a month and it has already gone from 3/4 to almost 1/4 now. I don't know if this is normal or not but I'm looking for some advice on two fronts. First, what's the best way to refill the liquid? Should I just unscrew the top? I know there is a lot of pressure in there. I just don't want to damage anything if that's incorrect. Secondly, is anyone using anything besides water? What are you using and how much of a mess is it?

Thank you!

Normal for mine too. I just unscrew the top. I use water.

I just unscrew the top slightly to vent it and let the water from the reactor push back in and fill it.

So you don't have a check valve above your bubble counter?

I just leave mine empty now. It evaporates too quickly.

So how do you measure how much Co2 is entering your tank?

Bump: So is there anyone using anything other than oil? Just wondering if it would save the hassle of refilling all the time

My CO2 is monitored with a reefkeeper controller. It measures and turns on/off the CO2 as needed. I have a drop checker for a quick visual check. Once it is set, it really doesn't change.
Glycerin is a very common option. Or just go with Distilled Water(to avaoid mineral deposit)

No, it's between the bubble counter and the needle valve. Maybe I have it in the wrong spot but I'm not worried about the bubble counter getting water in it.
