No. There is one in-built to the bubble counter to protect the solenoid, but between the bubble counter (attached to my CO2 cylinder) and my aquarium, the 1.5m of tubing, there is none.

Where do you normally fit one? Is straight next to the diffuser what people do? Will that prevent the diffuser from filling with water? I can see how it would stop the tubing from backfilling with water, but not clear to me how to stop the diffuser from filling with water. I can imagine that it would fill alot less if I fitted one next to the diffuser.
