Do I have a leak or something else wrong?

I just noticed this plume like thing coming out of one of the vents. I really don't know how else to explain it so I put this video on YouTube

http://youtu.be/BypBdo49itE Does this indicate a leak, another problem or is this normal?

There are two pumps and neither was running when I took that video and the pool isn't heated except by that wonderful Arizona sunshine.


Thanks, any input appreciated.

Thanks hotajax. But according to the manual it's a sand filter. Triton II TR100C

Interesting video.

What is displayed is simply clear water with a different refractive index than the rest of the pool water. I can think of at least three possible reasons:
1. You have a heater, and it is firing.
2. You have some sort of chemical feeder active.
3. You have a SWCG that is operating.

A leak means water is leaving your pool. Unless you are losing water, you don't have a leak.

Thank you for the detailed reply but I have neither a heater nor a chemical feeder. As for SWCG not sure what that is.
