Water boatmen insects in our pool

[kinetic (Steve)]

I wasn't sure where to put this video, so I put it in the terrestrial section.

We have these swimming in our pool, the last few tough ones somehow
surviving the 5000 parts per million salinity and chlorinator.
That usually kills em.

I tried my waterproof housing today on the GoPro clone I have,
to see if I could make use of the 60 fps setting and 'slow down' their action.

See here for full speed swimming:

and here for slowed down to 0.125x

.....and I thought the noise outside was just the pool pump humming....

Don't worry about them Steve. You only get them in clean water and trying to keep track of them is a good eye test.

Yep, we've had them as well although I haven't seen them for a while...
