Hello.
To make Zooplankton I don't need Phytoplankton (Chlorella).
I have different kinds of Paramecium,(Aurelia, Caudatum and the big one Spirostomum).
In my culture I don't need Chlorella just bacteria .
Like if you want to make lots of infusaria, you just have to take a small bunch of hay and you put in a bucket and after 1 week you will have million of infusaria, you don't need light.
So what do you think to make a Black-out (I hope it's the right term) no light, for about 80% of the little pond, for my Yellow perch larvae, no more filamentous
A+
