For the DIY bubble counter: find a small bottle, spice jar, etc. drill two holes in the cap. Place one line from the co2 yeast bottle in one hole, and use another line that goes into the tank. Alternatively, Drsfostersmith.com sells an approx. $15 bubble counter.
With a Nano, your best bet is filter intake. or just to dose Flourish Excel for carbon source.
