I’ve been adding Brightwell aquatics microbacter 7 daily since beginning the cycle. Last night I added 90 drops of Dr Tim’s ammonium chloride, which should have brought the level up to 1ppm per the math on their bottle. Went to bed with 0 ammonia reading. This morning the ammonia badge was dirty yellow, but wasn’t at the alert level, so less than .05 ppm. Tonight, 24 hours later, the badge is back to yellow. I’m checking .05 ppm nitrite and 2.5ppm nitrate. So we’re moving right along! Might add ammonia again tonight.
