I hate to add to this because what I have to offer it is unfounded, unscientific observations. But....

I have been running my Nitrates at 20ppm, Co2 at 30 to 40 ppm (Kh/Ph method) at P accordingly. With ADA aquasoil and powersand in my Mini-s (2.5g) with the 27w Mini S light at 8 hours.

I would clean the GSA and BBA bi-weekly and couldn't get the tank to settle.

2 weeks ago I did a good cleaning, dropped my Nitrates to less then 10ppm (tap measured at 10ppm with AP test), dropped my Co2 to 1/2 the bubble count and stayed constant with fleet, Brighty K, and Step 1 dosing. The thing is running so much clearer now. I just have a tiny smidge of gsa and the BBA is receeding. Plus, as Jason noticed, growth has slowed a bit but it's pretty dang good looking.

Now, I'm not offering up these numbers as proof of anything. All I'm saying is that in my instance running lean, alla Amano, worked in my tank with my water. I'm curious to see Jason's write up on his findings. Plus, as Jason said, I'm finding it easier to balance.
