So, in an effort to help clear up this whole chelated copper mess, I reached out to the mfg of Copper Power about their 2.5ppm recommendation:

COPPER POWER:
Thanks to @HotRocks, we are now reasonably sure that the mfg of Coppersafe has been giving inaccurate dosing information; whereas Copper Power’s dosing instructions appear to be spot on. Here is the thread in case you missed it: https://www.reef2reef.com/threads/c...instruments-high-range-copper-checker.368943/
Therefore, let’s summarize:
At present time, your best option is to “pair” using Copper Power with this Hanna High Range Copper Colorimeter as per @HotRocks recent experiences: https://hannainst.com/hi702-copper-hr.html
Your old bottle of Coppersafe is still fine to use, but use the Hanna Checker to verify the Cu level is between 1.5 - 2.0 ppm.
@HotRocks Since Copper Power seems to be fairly consistent, can you provide our members with dosing info to achieve both 1.5 and 2.0 ppm? To use as a starting point... (I’m assuming Coppersafe is too inconsistent to provide the same information.)
PLEASE NOTE: This information is fluid and subject to change. For example, we are still awaiting confirmation from @Hanna Instruments that their HI702 colorimeter works in the presence of saltwater. Once this has been confirmed, stickies will be adjusted to reflect this new information. In the meanwhile, please bear with us as we attempt to sort this all out.

Hi Alice - I have one further question, if you don’t mind.
Is it absolutely necessary to treat with Copper Power at 2.5 ppm? That seems a bit on the high side. In my previous experiences with using chelated copper, 1.5 - 2.0 ppm has always been the accepted therapeutic range.
If 2.5 ppm is necessary, can you please explain why? Why does Copper Power require this higher therapeutic level?
Best regards,

Hello Robert,
1.5 ppm is an acceptable level. We only advise using Copper Power at 2.5 ppm if necessary. It will still be safe at that level. Monitor levels at least every three (3) days for 2 weeks during an outbreak. Most parasites have a 12-14 day life cycle.

Therefore, let’s summarize:
- The therapeutic range for chelated copper is 1.5 - 2.0 ppm, regardless of product.
- DO NOT TRUST Coppersafe’s dosing instructions.
- DO NOT FOLLOW Copper Power’s exact dosing instructions, as doing so will slightly overdose the Cu level to 2.5 ppm.
