sera flore sound
I have a sera flore 500 co2 reactor. Lately I've noticed it makes a sound like running water. Both when the co2 is running, and when it's not. I've tried tipping it upside down to purge the co2 out of it. But the sound returns.
Any ideas on how I might get rid of this sound. I gotta say, it's really taking away from the tranquilty of my tank.
