go get a bag of miracle grow organic choice potting mix from your local hardware store
you can screen out some of the larger wood pieces if you choose, I just rip the bag and pour
soak it, cap it, fill with water
be prepared to do a few big water changes as it will leach tannins for the first week or so
Is miracle grow organic the best as far as potting soil goes for a planted tank? I don't mind spending a little more if there is something better. Thanks for the info!
