Added fish and nitrates fell
I just added 6 rainbows, and a oto yesterday and nitrates fell from about 7.5 to about 2 or 3. Total fish count is 8 rainbows, 2 angels, 3 otos, 1 clown loach in 37 gallons. Does that make sense. Could it be because I turned my emperor 280 on high last night. Hope it helps with the reds.
