I bought a cheap foam filter to use in my as-yet-to be-established RCS "farm". (my bettas eat the small RCS; I'm trying to make a way for them to breed so I can have the larger ones in w/ the bettas.) How the heck do I set it up? The directions are in Chinese.
I hope this photo uploads.
Is that tiny thing by my finger the unput for a small an air hose? Can I attach it directly, or does it need a valve of some sort? What's up w/ that periscope thingy? Does something attach to that?
(The white stuff I'm using as a backdrop is actually a cat.)
