Has anyone here ever used "Api Copper Test Kit" ?? It says on the instructions that it reads both free and chealeated forms of copper in the water...BUT...there is only one color coded chart to determine readings...how do i know if its free OR chealeated??? thx! :S
This is literally all it says about chelated copper testing -
This test kit reads the level of total
copper (free and chelated) in parts per
million (ppm) which are equivalent
to milligrams per liter (mg/L) from
0 - 4.0 ppm (mg/L). Chelated copper
compounds are very stable and will
remain in solution for long periods of
time. Free copper levels will decline
rapidly and must be tested daily
personally , i wouldn't bother testing...just treat as directed..once treatment is finished do your regular 30% weekly water changes and any copper will be gone..
the med you are using should tell you what kind of copper is in it..that will be your test reading...
I have never used that kit, but from the instructions you quoted, I would think it means it detects either/ or , so that any form of copper will show up on test. I did surf the net a bit, seeing if there were better directions for that kit, but found none. I did however find a lot of negitive reviews about it; very poor accuracy, tricky reading, confusing instructions, etc. If I had one, I would return it to the store for a refund...in the reviews I read, a copper test kit by seachem was frequently mentioned as a better kit.
