Re: [Killietalk] Daphnia
After reading Dave Koran's post on his daphnia cultures, I just want to
remind everyone that there are two ways to get adequate oxygenation to
any tank or culture. The most common way is via surface agitation of
the water via a pump, and the second way is to increase the surface to
volume ratio of the culture by keeping the daphnia in shallow trays.
This works beautifully for me.
Also, by feeding a powdered food mix, although I do risk overfeeding
and polluting the cultures, if I am careful that is not a problem, and
I avoid the necessity of a second set of containers for greenwater or
paramecium generation. And if I do mess up, it is only one tray and I
have several going at a time. My trays are compact, silent, and don't
have to be plugged in. For someone with little space and no
inclination to setup extra tanks for live cultures, it may be worth
considering this lower-tech approach.
