Ammonia and Nitrite both read 0 on my API kit. Nitrate is indicating a concentration below the lowest color mark but more than 0.
Tank is still very tannin stained, but I'm making progress.
I added a few more critters:
4 x Endlers Livebearers. (Poecilia wingei) Three males and one female.
1 x 1.5" pleco. Not sure of genus or species, however it is not a common sailfin. It has white tips on its tail.
1x 1.5" Red Line Barb (Puntius denisonii)
