I ordered a generic canister off www.aquatraders.com the other day, and i purchased a generic canister for my friend. Apparently when he installed it and started runnin the canister, the widebar in there starting acting kind of funny. But the stingray was ok. When he woke up this morning, the ray was upside down dead and when he picked up the dead body, the skin was falling off due to ammonia burns. Does some1 know what happened? The canister and its media was properly rinsed before usage of course. Thanks in advanced. BTW he did not change filters, he had an emp400 runnin and just added the canister on top.
 
Was every part touched by the water rinsed thoroughly? I have never heard
of an incident like that before.
 
Man, that sucks!

the ray was upside down dead and when he picked up the dead body, the skin was falling off due to ammonia burns
Does your buddy have the proper training/experience for that diagnosis? What were the exact ammonia levels? Were other fish affected at all (e.g. did the widebar still act strange)?

I have never heard of that. Hard to believe that it was a chemical, which is why I asked for the ammonia levels. And even if the ammonia was high, it could have come from the rotting ray.

I rather suspect electrical malfunction, a common cause of failure of non-namebrand equipment. Maybe the canister introduced a current strong enough to kill the (electrically sensitive) ray. Is your buddy's tank grounded?

Another sad example that cheap equipment kills fish :(

I was thinking an electrical problem also....

I only use cheap stuff for my cheap fish. sorry bro!
 
It is a 40 gallon tank. The emperor400 was running for a long time and it still is. He never took it down. He just simply added the canister. The ray was fine for months. There was a widebar and a nile perch in there with the ray. The canister was installed at 1 in the morning and 5 hours later (between 5-6 in the morning) he found the ray simply dead with ammonia burns all over. The widebar and the perch is fine now.
 
Good ole' aquatraders, more than likely it was an electrical problem, everything they sell is cheap for a reason. I bought a metal halide system from them for my reef tank and it almost burned down my house.
 
Sounds like they aren't a very reliable place to buy things from.
