I think adding more TurboStart at the 2nd stage of the cycle helped the nitrite to come down faster. One thing that I did notice I didn't do when I added it first. I didn't shake the bottle May have not had nearly enough of live bacteria to start with and that's why the nitrite cycle was so strong and "longer" than expected.That’s what I keep telling myself. Tank looks bad! Hopefully it will be sooner than later.
How was TurboStart? See any changes?
