Seeding a tank

[Myka]

Bags of "live sand" only contain nitrifying bacteria. It's really not that "live".

I'd suggest you get a ball of Chaeto off someone - it is usually loaded with critters. Once you're done seeding just throw the ball out or give it to someone else

I had a whole jam jar full of critters until a few days ago. Wish I'd seen your post. I am taking cleaning out a couple of tanks this weekend. PM me if you'd like what I find. Worms, etc.

In the meantime, I highly recommend Stability.
