Re: [Live-foods] Daphnia floating?

Hi c4g

The super saturated water most likely came from the tap.  Did you add tap
water or aged/aerated water to the culture?

Over aeration may cause this problem to if you end up with micro bubbles
everywhere from a fine stone. 

I'd aerate with a piece of rigid airline not an air stone.

Did you add super saturated water to the culture? Gas can come out of
solution and lodge in their shells.  Can you see bubbles in them?

Super saterated water would be water with large amounts of algae or other
nutrients? Yes...I do see little bubbles in their bodies. Is there something
I can do to correct this? There does not seem to be as many floating here at
mid-day as there was this morning. I went in and helped to "dislodge" them
from the surface but there are still about a dozen from an approximate 400
culture that I purchased still on the surface and these are the ones with a
tiny bubble in them.
