I service a 90 gallon fowlr tank that at one point, years ago, had coppersafe in it. Since then, we have replaced the sand and used various absorbers (cuprisorb, polypads, purigen, chemipure) to remove any traces of the copper. Polypads continue to come out brown not blue, etc.
Even so, the tank cannot seem to house any invertebrates: snails are added and most seem to never move from their introductory placements until they die. The only invert that seemed to do decently was a larger banded coral shrimp, which was in the tank for at least 6 months before seeing it listless and slow to react (but still alive) today.
The only fish I was suspect of was the picasso trigger, but the owner seems to swear he never sees it attack anything. Only other fish are a heniochus and (breeding) pair of ocellaris.
The tank desperately needs invertebrates to survive for algae cleanup. Any ideas?
