Thank You Sir ! I thought that's what I heard. I have an old API test & copper hidden somewhere in my stuff. Just as well. I have been extremely lucky & haven't had to treat a fish yet. I do have 2 20 longs for qt . One of which is always going & ready for a fish . I'm working on a med chest little at a time .
About to order the Hanna HR copper tester tonight like now ! It's the right one, correct?
I didn't see another type just wanting to make sure. I'm likely to screw it up !
