Nope no need to wash the bottles. If you use a yeast that floats, you can use a tube and siphon the liquid out from underneath the yeast.
I could count my bubbles...but I don't. Drop checker says 20 ppm right now, but that's cause I just recharged yesterday...yeast is still warming up. By tomorrow should read about 30ppm and stay that way for 13 more days.
I use EI dosing: KNO3, K2SO4, KH2PO4, and Plantex CSM+B for traces...all from Rex Grigg. I may start dosing iron as well, haven't decided yet.
