My Tank Thread
Very good to know! I'll probably invest in one. It's kind of a dream come true to see a number pop up rather than strain the eyes and wonder if it's really a shade darker today or if I'm just crazy (even with the Chemetrics kit). I think I may be making the switch to Copper Power regardless at this point. Too many inconsistencies with the Fritz product to seem worth it. As a curiosity, do you happen to know if the Hanna checker can be used to test ionic copper?
For those of you that had inquired. Test works perfectly fine with ionic copper, I tested my cupramine. Dosed to what should have been .50 into freshly mixed saltwater this time. I skipped the fresh test just based on the fact that yesterday's test results didn't seem to vary outside of Hanna's variance for the device of +/- .05 either with or without salt.
Result was .54
The more I test, the more faith I have in this tester! I believe this device will be widely used in the hobby here soon, making it much easier for people to test all types of copper with one single device, in a very accurate manor. It's great so far, I will continue to play with it, and share my findings. I also reached out to Hanna today to share yesterday's findings and see if I could get any more info from them (I'm not sure I will get anything out of them, as I'm sure they won't be forthcoming with information until they perform their own testing, which is totally understandable from a liability standpoint). I will keep you all posted!
