| when is copper gone completely?
About Dec/Jan I treated my 55 gal with copper to treat ich, since then I have done many water changes and gravel vac on the crushed coral. I replaced carbon and added 3 bags of chemi pure. I do a water change of 10 gal every 2 weeks. Would it be safe now to add live rock and eventualy corals? I did a copper test and it read 0, but im not sure if there could be copper left thta would reactivate itself. Any help is appreciated thanks |
