Wow I didn’t realize so many members had major stock in Algaebarn. My bad guys I said “Possibly” in the title and asked for opinions sheeeeesh relax. Ok let me break this down a bit More so maybe it makes more sense as I “possibly” didn’t articulate myself well last time

My first attempt irradicating Ich I ran the tank fallow for 85+ days with fish in 3 separate aquariums (far from my display)for there were over 24 fish many and them large so a daunting task to say the least. CopperPowered them all for over 30 days at 2.0 and observed after the treatment until fallow for 85+ days was completed. I put the fish back in and several months later ich came back. I did not introduce anything into the tank not even a rock/invert. This approach did not work for me and I followed every instruction from well respected members here. My second attempt which was given the okay from Again,we’ll respected members here, was once again unsuccessful. “If it dries it dies” right? Can anyone dispute that? I dried everything and afterwards I soaked it in RO water for 7 days .The tank was empty and then I ran tap to rid of anything in there. New dry sand, dried my live rock then soaked in RO for a week. All fish were copper powered for 33days at 2.0. No cross contamination the QT was in the garage far away from display and all inverts were in a separate qt tank #2 (78 days fallow) opposite side of my house far from my display and fish QT.
The only thing I can point at is the copepods I purchased from algaebarn and/or resistant ich to copperpower at 2.0. Thanks for your replies and appreciate the ones who displayed a little bit of empathy through text after reading the absolute hell I’ve gone thru with my 265 full of angels, tangs, and wrasses.
