Re: Daphnia Observations
What do you do for water changes, if at all? How often, do you
change your water chemistry at all, etc.?
I remove about 2 gallons every 10 days or so. I siphon from the bottom,
removing the mulm. Most of that is dead daphnia, those that escaped my
netting. The food I use - soy flour and yeast - is all consumed and doesn't
leave a residue.
I have a feeling that I could get more daphnia out of these two tubs if I fed
more, aerated, and had more lighting. But intensive culturing also creates
more waste and other problems, and what I have is more than I need, so . . .
My water is hard and alkaline. That tends to be very stable. I've never
checked the chemistry in the cultures, but my tap water is 7.8 + and 230 ppm
Hope this helps.
