Well all fish are now in Ht. I had to take the rock out of my tank to catch them. What a mess.
This is what seachem said about the Quick Cure I used.
Thank you for your email. Formalin is a reducing agent, so it is important that it be fully cleared from your system before you dose Cupramine in the same water. Most often, reducing agents have broken down in the water completely after 72 hours. To be certain, I might recommend using activated carbon in your filter for a day to remove any lingering traces. After the formalin has been cleared from your system, it is safe to use Cupramine in your hospital tank.
That's what I figured, but getting confirmation from them is good to know. :thumbsup:
