You would want to get clean chaeto from algae barn or something
If you get it from someone else, you risk bringing their problems/parasites/etc. into your tank
Just my thought
I dont charge people for something I would throw away..... I think it started when you opened your mouth in a thread when someone was trying to help someone else out..
Could you please just put some in your mailbox in a ziplock bag and I can pick it up? I don't know your schedule and I am flexible during the day to drive to Karns to get it. What day works for you?
I really appreciate you.
