Some pics of the new culture as it arrived.
The rotifers still bagged, backlit by new main tank...

 
And the culture bucket...

 
Now to buy a simple USB microscope so I can actually look at these critters!  ANd I need a bigger fish room....

More aeration!  Double what your doing now.
 
Get yourself a Sedgewick-Rafter counting slide once you get the scope.  Then you can count your rotifers and be a step above most hobbyist breeders.  If you don't count, you really are flying by the seat of your pants.

Thanks for the input - I'll ramp up the airflow.  The water was much lighter this morning, so RG was added (I'm planning twice a day feeding).  I was surprised by this since the culture was so new.

I short video with my iPhone showing my first harvest (about 25%).  Interesting the way they congregate in clusters.  They can be seen swimming even without magnification (much more detail on my iPhone in hi def, but I didn't want to eat up too bandwidth just for this!)

Seeded my outdoor tub today after cleaning my indoor culture bucket. I used 2 gallons old existing culture to continue the indoor bucket, and added about 3 gallons NSW at 1.018 SG. I harvested the other 3 gallons to place in my outdoor tub. It is an old 5 gallon Rubbermaid container that has my excess chaetomorpha that I thin from my refugium. I have adjusted the SG down to 1.020 for the rotifers.

Trying to get some photo evidence for continuation.  I'm realizing how lousy my microscope image capture software is - the pics look much better on the screen, but when I save them, really crummy resolution.  My iphone video looks better than the still!

Here's the pic at 60x mag with my Celestron USB scope..... I have to get some better software, my screen capture is a lousy 640x480.

Ok, I finally got a decent microscope! Here is a pic of my rotifers at 32x magnification. I took this with my iphone held up to the ocular.
