So I'm getting Copper Power but I really don't wanna spend 65 bucks on the Hanna test. I've been thinking, the Salifert copper test looks pretty good and seems to be highly recommended around here. The only issue is that it only measures up to 2 ppm, when Copper Power works best a bit over that. So, why not simply dilute the water sample (as much as necessary) with tap water (after testing it and ensuring it has 0 copper itself)? For example, If I'm aiming for 2.5 ppm, I could take 1 mL from the QT, put it in a little cup, then add 4 mL of copper-free water. Being a 1:5 dilution, I would be checking against 0.5 ppm.
Thoughts? If you think this is a good idea, would you recommend seachem or salifert? It seems the salifert one is easier to read but maybe that's only because it has fewer in-between options.
