Given the history I think it's maybe time for you to bite the bullet and treat the fish in a tank without any rock/substrate and leave the DT fallow for 72 days.
Get rid of the problem once and for all.
Ich can hide in substrate and rocks, and treatment in the DT is quite hit and miss.
Use the test kit results. I have a sneaky feeling you may have overdosed
The clarifier may have dissolved the bonders in the copper causing number to rise.
we’ve seen others use recommended m/l or drops which was too much
Was this cupramine or coppersafe?
I have seen false results but it is rare
Coppersafe
Should I do a 20% water change or wait see if copper drops tomorrow

Did you test the tank BEFORE adding the coppersafe? Copper Power is very long-lived in aquariums. If you dosed it 2 months ago, the level of it will have only dropped by the amount of water changes you have done since then (30%?) then, if you add that amount to the amount of coppersafe in a full dose, you will get an overdose situation: 2 ppm - 30% + 2.5 ppm coppersafe = 3.9 ppm
I looked up the SDS for Clarity. It is just a flocculating agent. As such, it should not affect copper medications like their Prime product will.

Four out of the copper safe it’s been about two months since I use copper power and I get to water changes about 2530%. I want to hear the conversation I’ll check for copper give me the reading in the time. Thank you for the information.
Also realize that having your skimmer on - may have lowered copper some as well. You are likely going to need more water changes. i.e. if the level is at 5, to get to 2.5 you will need to do a 50 % water change
This is weird I did a 120 gallon water change on my 600 tank last night when it read 5.00 just now did a recheck with Hanna and got 1.17. Docent make sense!
Sounds like a previous false reading especially if copper was just added. What is expiration date for your reagents?
2027 want thank you for helping me with info on this, any suggestions on going forward. Thanks Carl
One suggestion: With mixed readings you've had, Take a water sample to a trusted LFS that does Not use Api copper test and have them test for you and see what they come up with and to compare with your readings.
I had a high "false reading" with copper power just last week due to procedure error on my part.
I used a 10ml glass dropper to add some copper power, then used the same dropper to fill my hanna test cylinder.
There was residual copper inside the dropper which caused me to have a very high reading. After rinsing the dropper I got a more believable result
