Brightwell cuprion.

HeadOnAPlate561 · Nov 1, 2016

Anyone used brightwell cuprion. I set up a 20 gallon bb tank, dosed 20 drops which should bring the tank to .20 ppm copper. Yet, my salifert test still isn't reading anything. Anyone have any ideas?

Have you tried double checking with another test kit? A friend or LFS? Maybe try a Seachem copper test kit instead.

Are you waiting the full 20 minutes after adding the reagent?

Yes waited 10 min, 20 min, and 30 min. still nothing. after which I took about 4oz of clean tank water put 3 drops of copper in tested it and still nothing. so either the test kit doesn't work or something else. any ideas. going after I get off to get the water tested

could be a bad test kit. Wait to see what the other kit says about the copper level, then decide if you need a new kit or a bottle of copper..... or possibly switch brands (probably not needed here)
