IN the past 3 days, I've had my Melanarus go missing, a male percula start acting like he's had a stroke (a day of hanging out in the corner near the surface of the water, now he's hiding under a rock and breathing very heavily) and my mystery wrasse go into hiding (usually a very active fish that eats like a pig now won't even come out for brine...I can see it and it seems to be breathing normally). The only change in this time frame was adding BRS GFO to one of my reactors. I rinsed it by running tank water through until it ran clear (always do) but it seems like the trouble started the very next morning.
I've heard some rumors of unrinsed GFO causing problems with fish...wonder if this is related? I'm pretty unhappy to be losing 3 of my favorites all in a few days time [smilie=crying.gif] Has anyone else seen something like this happen after adding GFO?
