48 hours after my partial
water change, my
aquaponics tank experienced lift off! The nitrite reading had been
stubbornly sitting at 0 since the beginning, but abruptly that light
turquoise changed to a very faint violet. Progress! Looks like those
critters are finally getting to work now that the pH is closer to
proper values. (I actually overshot and went too low this time, but I
think it's going to even itself out...or I'll add a bit of well water
to bring us back up to speed.)
Meanwhile, the grow bed
is really greening up. The chives have grown nearly two inches and I
think the celery might be putting out new leaves. I'm excited to see
how quickly the plants and bacteria work through the nitrogen and how
well the ecosystem stabilizes now that it's gotten its start. Once the
ammonia disappears and then disappears again after I add a second dose,
I'll consider adding fish!
