this caught me by surprise. I had my pumps off. I have a nero pump ( on a low setting) and a regular system pump which were off because I fed the clown fish and I turned them both on at the same time. I'm glad I saw it because I guarded it against my prized coral. But I still cannot find my bta. ( that one disappeared since yesterday when I turned off the LEDs the whole day, trying to assuage some cyano.
