I start them in 1.50ppm and take them up to 2.0ppm over a few days.
I've never started anything that high. But with the apparent increasing resistance, I understand why.
Eventually it won't work though.

I understand. Previously I always started at zero or 1.0ppm. Honestly though starting in the 1-1.5 range I have had more success than starting copper free.

Honestly I use the same process and Cu level for all fish. I've treated several Wrasse including leopards and anampses. Never have an issue.

I start them in 1.50ppm and take them up to 2.0ppm over a few days.
well im going to get my stuff tested again this week from a hanna at the local fish store, also have you ever seen or heard of this, my yellow tang been hiding non stop in little house i have in the QT, came out this morning and his dorsal fins right when it connects to the body look black/ brown? any idea what that is or how to heal it maybe

It sounds like possible bacterial issue.

any way to help heal it during copper QT?
Can you upload pics? I am guessing hard to get if fish is hiding. You can add antibiotics to copper. Kanaplex and Furan-2. I want to make sure it is an infection though before you add them.

realistically does my display tank need to be fishless for 6+ weeks or woule 3-4 be enough i see people saying 75 days fishless ...

6 weeks eliminates almost everything. There is a study out there that had ich surviving longer than six weeks which is where the 76day rule cones into play.

6 weeks is the minimum timeframe. Then it boils down to your personal tolerance for risk after that. I do use the 76 day rule my self.

Hi all - are y’all recommending 2.0 - 2.5 PPM now if you are doing 30 days in copper?

@HotRocks Help! I am in dire need of your math/chemistry knowledge. I'm not exactly sure how, but I accidentally overdosed an 8gal WC (25%) with Copper Power. I have not added the WC to the QT and I also don't want to discard the treated 8gal WC. My Hanna Checker test of the WC reads 3.31. My QT is currently at 2.01. How much new saltwater do I need to add to dilute the WC to match QT? Please help!

Add 3.25 gallons of fresh saltwater to your WC and it should get you darn close to 2.0ppm!

Thank you. For my own notes, can I ask what formula you used to calculate?
Ok first, figure out what percentage needs reduced. You want to take 3.31ppm down to 2.0ppm

So you need a reduction of 1.3ppm.
1.3ppm/3.31ppm = a reduction of 41%

Now take your 8 gallons × 41% reduction. That's how I came up with adding the 3.25 gallons.

Thanks. I seem to remember learning how to do percentages like this in school several decades ago. My 15yo son just walked out of the room laughing. (I'm assuming at me.) o_O

I had to think about it for a minute. Because I don't usually have to add water. So he'd be laughing at me too! ;Blackeye

Should I be ramping up slower?

I put a Lemon peel angel into QT and started dosing CP at 3ml per day (10-gal tank). The goal was 3ml treatments over 4-days with a target of 1.9 ppm. On day 3 he was dead, didn’t do a reading but it was probably around 1.0 ppm. Was I ramping up too fast? BTW, tank parameters were fine.

@HotRocks hey buddy so my tang is in copper for about 25 days now at 2.0 - 2.2 do think i can do normal water changes without keeping the copper at 2.0+ and slowly reduce ( ammonia catching up to me ) or should i still keep the copper level high
