First, a few disclaimers:
After getting the green light/more confidence from a chemist about this, I began experimenting on fish by mixing Prime + Copper Power in a QT. I did this repeatedly on different batches of fish, got the copper level as high as 2.5 ppm, tested daily, dosed Prime daily and all the fish are still fine. Not once did I see a spike in the Cu level after dosing Prime using the Hanna High Range Copper Colorimeter (HI702).
So, I feel it is safe to use & recommend mixing Prime with Copper Power to control ammonia on an as needed basis.
- This only applies to using Seachem Prime with Copper Power.
- I have not tested any other ammonia reducers with any other forms of copper. Seachem, for example, states right on their website that it is dangerous to mix any ammonia reducer with their Cupramine copper product.
- The manufacturer of Coppersafe (Fritz) has told me that it is safe to use with ammonia reducers as well, but I have not independently verified this.
