Subject: Copper aquarium question
To: killietalk at aka_org
This week I listed a solid copper aquarium on eBay, item # 2354832197
and I have a question. Since it is solid copper and has no glass and
the water is in contact with the copper sheeting, is there any danger to
Yes. If the water becomes at all acidic (often happens with age), the
copper can be etched into solution and could reach lethal levels.
Also, if it were coated inside with a water-based vinyl or
poly finish - and allowed sufficient time for drying & curing - would
this adequately inhibit the copper problem (if any) and would the
coating itself create a different problem? I've used it (some) for
aqua-culture (plants) only and I don't want to kill or harm anybody's
fish. Thank you.
The only safe finish, IMHO, is a two-part marine epoxy that does *not*
contain any anti-fouling ingredients (and applied in multiple coats with
setting up between them). The others will never be totally safe and may
cause their own problems.
Sorry to be the bearer of bad news, but copper and fresh-water fish just
do not mix well at all.
