A tank I recently bought came with one of these Up Aqua CO2 inline atomizers:
Except, I haven't seen my drop checker change color no matter how high I crank the bubbles per second. I also have steadily been increasing the working pressure, in case that was the problem, but I have it pretty high now (as you can see below).
I thoroughly cleaned/soaked it with bleach (injecting bleach into the CO2 area with a syringe even) and still nothing on the drop checker after a day of letting it run...
A week later, I ordered a new one thinking the old one was just broken or damaged.
I've had that hooked up for a few days now and still nothing.
Here is what my regulator settings are at:
I moved the drop checker into my big tank to make sure it was still working - within an hour it was turning yellow, so I'm pretty sure that's fine.
I also removed the CO2 tube from the atomizer and stuck it directly into the water, and I can see the bubbles coming out - so I am fairly certain they are at least reaching the atomizer...
What am I doing wrong?
