LOL - Yea, you can have the Chaeto. I didn't list it as I was going to toss it. The fuge does have flatworms.
However, a 30 sec rinse in RO/DI water would rid the chaeto of the flatworms (they will simply explode) as well as any pods and leave the chaeto intact.
The reason I'm tearing down the fuge is that I'm going ZEO and it would only be a matter of time to the point when this system doesn't contain enough nutrients for macro to grow and it would die on my anyway.
Yours if you want it.
