I got it in my DT. Every night at 10:00 p.m. I turn the lights off and the moonglows on. Every morning at 7:30 a.m. I turn the lights on and the moonglows off. I have given oodles of it away and my yellow tang nibbles it constantly. So from my experience, I would agree with the others here: it should be fine. BTW, my nitrates are nearly 0. My master test kit barely registers any at all. So not even 5.
