Re: DP Daphnia Magna and Euglena (greenwater) help needed

Suggest forgetting the horse manure for use inside the house; instead, 
put it in an outside container, along with natural pond water,  in full 
sun to create green water.  A large tank works well.  Bring the green 
water inside to feed the daphnia.  As their growth is highly temperature 
dependent, warmer temps = more daphnia.  A yeast solution is good for 
supplemental food but should not be used exclusively as it does not 
provide balanced nutrition.  Also suggest adding some crushed oyster 
shell to the daphnia culture as growing daphnia deplete dissolved 
calcium to build their shells.  As you harvest the daphnia, calcium is 
taken out of the system, which must be replaced.  Oyster shells dissolve 
slowly, add more when needed.

As far as the euglena are concerned, just put in full light and feed 
infusoria from a container with decomposing lettuce leaves. Again, 
culture the infusoria outside and add sparingly, as needed. This reduces 
the potential for odor problems inside the house (and preserves space in 
your fishroom for the important things - FISH !!!).
