Sarah88;4170183; said:no i dont think its nitrates either, as their behavior isnt really how a fish would act with high nitrates but its always good to know what your water parameters are. and you said that your ammonia was 0? does your de-chlorinator also take care of chloramines? im not sure if greensboro uses chloramines or not but its always good to use a product that takes care of both chlorine and chloramines like prime. if its not ammonia or chlorine/chloramines then it was probably gaseous build-up from your gravel, when was the last time you had thoroughly vacuumed it before this? gravel beds you should always stir up and vacuum thoroughly to prevent gaseous pockets from forming (same with sand about keeping it stirred up)
Just tested the trates, and they came back <20ppm, so no surprise there.
The only thing that throws me on the gravel is the fact that the two reg Oscars died one right after the other, before I ever touched the gravel. The Albino finally passed today. He exhibited the same symptoms for about two days longer than the others, before dying, but obviously lived symptom free for about a month.
One other thing I forgot to mention, was that I had been moving things about in the aquarium quite a bit. I was trying to get things in the right places, and get rid of a little brown algae in some spaces I never fully removed from the original cycle, so my hands and cleaning tools were in the tank alot during this time. You think this could have been caused by good ol' fashioned stress?
My filtration btw, is an AquaTech 30-60, but I'm prolly gonna pick up a Ehiem 2234 soon.
