So after loosing everything to a parasite I have been empty for 43 days as of today. I have two clown fish in my QT that will have been in there for two weeks this Saturday. I have been working hard to remove the copper with both Chemipure and Cuprisorb for over three weeks and am down to nearly .1 in the reading. The clown fish are new and have never been in my DT. From everything I have read my DT should be safe to add fish again and I was planning to do so this Saturday which will be 45 days fallow. What is the consensus from everyone? Just FYI i had Velvet that I eradicated with Copper Power from an infected Niger Trigger then an infected Emperor Angel had an internal parasite that killed everything in two weeks. At first I tried Prazipro and then General Cure but it was too late by then I guess. Lost those two plus a small Clown Trigger. Very costly losses so I'm going a lower cost rate of fish this time. LOL
