I did a little experimentation last summer with using "green water" that spontaneously developed in a bucket in my backyard as a basis for raising cladocerans, clam shrimp, and redtail fairy shrimp. My available microscopes were not quite up to the task of producing an identifiable image, but it looked like it was mainly a single-celled flagellate, possibly a Chlamydomonas species. It worked very well as a food for cladocerans and fairy shrimp. I wasn't able to hatch many clam shrimp. This season, I decided to start with known organisms, so I obtained a Chlamydomonas culture, and a Euglena gracillis culture. Euglena is slow to culture, but reaches very high cell densities. The Euglena cultures have not had enough time for me to be able to evaluate their success yet. Chlamydomonas is much faster. It is doing well on dechlorinated tap water with 15 drops of liquid Miracle Gro per quart in a sunny window. When it warms up a bit, I will start some 5 gallon buckets outside.
