Tiny waterspouts forming

[TheDrB]

Not sure if this is a bad sign or if I just haven't seen it yet.
I was getting an odd gurgling noise, and when I got a chance to check it it was ittle water spouts forming and then making bubbles when they would intersect the return stream.

Is this anything to worry about?

Thanks,
Jason

They are whirlpools and are created when your return flow is too close to the surface. Point the return downward or put more water in the pool
