No, nothing went through the powerhead. Yeah, the RBTA is my guess. Those things keep growing and growing and not splitting in my tank. They are monsters.
Sadly, I lost a well established fat dwarf angel as a result of this. There isn't an ammonia spike yet. The inverts appear to all be fine so far. I measured the oxygen this morning at 10:30 and it was only 47%. Obviously, night time oxygen would have been even lower. I haven't run a skimmer in over a year and had meant to start it up again. Just didn't get around to it. It would have helped oxygenate the tank. In hindsight, I should have kept the lights on overnight to prevent the oxygen levels from going down.
