A word of warning. I don't know if any of you read my recent post in the Regal Angel thread. But my quarantine tank somehow "crashed" but when I say crashed I don't mean in the normal way. All of my readings were at zero and my pH was 8.2. Yet many of the fish in my quarantine tank just dropped dead, even ones I had had for months in there like my juvenile french angel.
I'm pretty sure it was the piece of sponge I got at the wholesalers. Part of it I put into quarantine for my new Regal Angel to pick at, which he did, the other bigger part I put in for my Idol (which he didn't touch or even seem to care about I might add).
After that disaster in my quarantine I took the sponge out of both of my systems because I think it must have emmited some kind of toxin into the water. I can't think of anything else that would make my fish just drop dead like that with nothing wrong with my water parameters. I just hope the bigger piece didn't effect my main system with my Idol in it and I hope my Regal lives. Although everyone seems to be just fine at the moment.
So in the future guys, be careful what kind of sponge you put in your tank for your Idol if you choose to do so. I mean, this is a sponge I got at the wholesalers!! I didn't realize it but there is an article in the RK mag this month about sponges. And I think it mentions their possible toxicity. Glad I know this now. Just too bad I had to lose fish in the process of learning!
