Where Did All The Nitrate Go?

Check out my other channel, "Dan's Outdoors And More" at the link below: https://www.youtube.com/channel/UCO3bQauFz2WL14Qxs_PY6-Q I believe my "Native Tank" aquarium has developed denitrifying bacteria. I have no way to explain why the nitrate doesn't build up in this aquarium. As far as I know, wood does not remove nitrate. As an Amazon Associate I earn from qualifying purchases.
