So as much as we have tried not to we have managed to get ich into the DT. I know the normal process would be to remove all fish and place in a QT to treat, however for me it would be much easier to remove the 5 pieces of coral, 4 starfish, 2 BT anemones, and the random snails and hermits I have and treat the DT. DT does have rock and sand...rock was just put in about 2 months ago after we pulled all the rock to redo it. In doing that we gave all the rock a muratic acid bath as well. If I were to remove said inverts and dose Cupramine in the DT and follow that up with Cuprisorb and poly-filters until there wasn't any detectable copper in the water I'm thinking I would be ok. I know that rock and sand can absorb copper, but I was thinking that after the Cupramine was stopped and I'm using the Cuprisorb and Poly-filters what ever they did absorb would just leach back into the water as the copper was removed. Am I way off or should this work?
