Re: Detergents (was LFD V3 #159
Hello Tomoko,
Unfortunately, not all detergents are created equal! Some are almost
benign, other quite toxic, particularly to invertebrates. But that does
not help you much!
Not knowing your exact situation, I am going to tell you what I would do
in analogous circumstances:
After rinsing the container in tap water (assuming your tap water is OK)
I would fill the container to the brim and let it stand overnight, then
empty it.
Fill it with water you going to keep your Daphnia in add a bit of food
and a FEW Daphnia. If the Daphnia are OK after, say, 2-3 days, then the
container can be assumed to be "Daphnia safe".
Good luck!
George
