I used to own several newts and had success with them for about two years. Suddenly my five newts started dying off. One died and then around a month later the rest died in the span of around a week. After the first one died (a california, warty dark brown above and gold below) My roomate put an active charcoal filter in there to improve water quality. I've always suspected that this was what suddenly killed the rest of them. None of the deaths had any obvious symptoms except the first(a blister). Anyway I was pretty distraught over the whole thing and switched to tree frogs, with success. I'm kicking around trying newts again, but need to know what happened last time.
Could the filter have killed my newts?
If more information is desired I'll give it.
