You can use water in your bubble counter but people like mineral oil because it doesn't evaporate.
I'm not sure why bubble counters will be useless? How would you know how much Co2 you're pushing out? Are you going to sit there and gauge your plants and fish or wait the 2 hours for the drop checker to change?
I'm not directly asking you that question, it's more so on whoever says it's useless. It's useless in the sense that my bps is different from your bps if we have two different set up.
Bubble counters are great for monitoring if the rate of flow is changing, not great at describing the amount of Co2 in the tank. What I mean is, if you're set up is at 1 bps and the next day it's at 1.5 bps and changes on the third day, you will see the changes right away in your bubble counter.
For the GLA primo setup, you would have to ask them about that. Maybe they don't want mineral oil to leak into the flowing water, it would probably clog your inline diffuser.
TLDR; Bubble counters are useless at describing the Co2 in your tank compare to someone else, but they are great at describing the amount of Co2 you're releasing with the needle valve.
