I currently have a 20 gallon long I used as a Quarantine tank but my build for the larger tank has stalled so the fish have been living in the tank. I started the tank around 11/1/17 and used copper for about two months. I want to make it more inhabitable for them while I finish the larger tank build. Using a copper test the water is clear of copper so I wanted to know if I could put rock and possibly corals in safely or do I need to change all of the equipment and use a new tank. I've changed the water at least twice since I stopped using the copper.
Thanks in advance!
