Looking at @Jay Hemdal 's 2021 qt guide, he notes copper safe needs to be at 2.0ppm minemum. Does this also apply to copper power? I always was under the assumption that 1.5ppm was the minemum.

I ran some initial testing, and when dosed according to label directions, Copper Power tested out at 2.1 ppm. Copper safe was around 2.35 ppm. I do need to run some additional tests though, to increase the sample size....Looking at @Jay Hemdal 's 2021 qt guide, he notes copper safe needs to be at 2.0ppm minemum.

I strongly disagree with the idea of running copper at sub-normal doses. Too many times I’ve seen that fail to affect a cure. The only time I ever suggest that a when a person lacks a good way to test for copper....I always went 2.5 with copper power as directed on the label but I'm pretty sure it was humblefish who said lower levels were effective when using chelated copper. Even if 1.5 ppm was the minimum I'd go slightly higher to avoid any momentary dips during WC or a small overfill in top off dipping the level. I think 2.0 is safe and a good level to shoot for.
That makes sense, it'll give them a little buffer that way.I strongly disagree with the idea of running copper at sub-normal doses. Too many times I’ve seen that fail to affect a cure. The only time I ever suggest that a when a person lacks a good way to test for copper....

It doesn't matter if its 8000 gals or 8 gals, CP levels are what they are regardless. At 1.5-1.75 they are just keeping the Ick and Velvet at bay. It isn't getting rid of anything. At those levels it just makes the fish look good. If you want to rid the fish of Ick and Velvet, keep them in a 2.5 CP level. Bacteria and such is very good at adapting.For reference this is on an 800 ish gallon lfs store system (I work there part time). I've never seen a case of ich break out in the system and the copper power is usually 1.7ish ppm (varies between 1.5 to 1.7# ish range).
im going to be using copper powder blue for my QT tank to get my fish into shape before going into my tank, i currently have the QT set up and im buying a few fish ill want in my DT but i want to make sure they dont have ich so ima keep them in there for a good 30-60 days what is a good test kit thatll work on copper powder except for hannaIt doesn't matter if its 8000 gals or 8 gals, CP levels are what they are regardless.

Salifert i think is fine, not 100% sure on that one thoughim going to be using copper powder blue for my QT tank to get my fish into shape before going into my tank, i currently have the QT set up and im buying a few fish ill want in my DT but i want to make sure they dont have ich so ima keep them in there for a good 30-60 days what is a good test kit thatll work on copper powder except for hanna
30 days is sufficient for CP. if you want to go 60 days, I’d suggest using coppersafe.im going to be using copper powder blue for my QT tank to get my fish into shape before going into my tank, i currently have the QT set up and im buying a few fish ill want in my DT but i want to make sure they dont have ich so ima keep them in there for a good 30-60 days what is a good test kit thatll work on copper powder except for hanna
The only tester I trust for Copper is the Hanna. I think Salifert makes a good test kit, but not sure.im going to be using copper powder blue for my QT tank to get my fish into shape before going into my tank, i currently have the QT set up and im buying a few fish ill want in my DT but i want to make sure they dont have ich so ima keep them in there for a good 30-60 days what is a good test kit thatll work on copper powder except for hanna
I'm not positive, but I think the Salifert kit only works with ionic copper (so a range of 0.0 to 0.25 ppm). I wish there was a good copper test for amine-based coppers, but I haven't found one other than the Bicinchoninate test that the Hanna probe and spectrophotometers use. I can get good readings on the API test kit, but only when I read the results in my spectrophotometer, when I try to eyeball it, it isn't accurate....The only tester I trust for Copper is the Hanna.
