Did somebody say milk jug??
I am not going to read all that but for phyto to help "consume" ammonia it will require a high rate of photosystesis to achieve that, a strong light that many larvae tanks lack.Even phyto cultures can have ammonia sometimes.
youre killing larvae and deer too? so much for the enviroment...

Actually Luis, I froze them (stuck 'em in the freezer) before I shot 'em...they DID take a quick freeze and keep ticking.
Ed, I apparently kill all sorts of stuff. Only wounded the deer...I think the guy who shot it twice is ultimately responsible - and FWIW the deer wounded my brand new car too

Actually, I'm not sure they were alive...I frozen 'em solid and they thawed out under the scope. I think actually the freeze did kill them - it was a short freeze, on the order of a couple minutes at most. But I can say that I don't think they changed in size at all.
The reason for the confusion now that I'm reexamining what I did is that I stuck them into the freezer twice....the first time didn't slow them down long enough, and the 2nd time I KNOW they froze solid and when it thawed I shot my pics, then moved on. So perhaps, they may or may not have been alive at the time of photographing.

Luis, I brought some A. tonsa from my culture to Joe L. this evening...he's gonna put them under his scope and measure them...I'll let you know what he finds out. He's also going to check into and measure the SS Strain I have - I have to say, at initial glance, his look smaller, but on the flipside, I'm culturing SS at an average 68F, whereas he's a full 10-11 degrees F. warmer! I know from experience that SS when cultured in the larval tanks gets REALLY small.
