Of course you know by now that I'm always one to worry...
If you're using the miracle gro organic potting mix, it can and does release quite a bit of ammonia at first. If I'm remembering correctly, D.Walstad recommends this mix because it lists the ingredients on the label - and chicken poo is organic. lol, double check that, it's been a while since I read up on it before dirting the 20. I'd be pretty leery of adding it directly to a stocked tank, and would definitely
want to mineralize it first to make it safer for the babies. . . if you plan to screen it, which you'll have to do to get the texture of mud, be prepared to lose a LOT of soil. I want to say I ended up removing at least half of each bag of soil - though what was left after was sooooo lovely and soft! I know both Boredomb and BWG have used this soil in their tanks, they might have more input for you, if you need it.
Good luck with the freezer method, if you go that route - can't wait to hear how it goes!
