Proper dose for cupramine?

[Travis Jackson]

So everything I keep finding says I should have my cupramine level at .5ppm but the bottle says .5mg per liter. So I have a copper Hanna checker, cupramine and a 20 gallon tank. So should my final reading be .5ppm or should it be .5mg per liter. Which would end up being 37.5ppm.

.5mg/L=.5ppm/L
20G=75L
So .5mg/L would be .5ppm×75L=37.5ppm
Maybe I'm just over complicating this idk?

Final reading with copper hanna checker with cupramine should between .5ppm - .6ppm to be most effective

Ok thank you. What I thought but directions are little confusing.

I'm glad you asked. 38 ppm would kill your fish quick

Yes that's why I didn't want to start dosing any copper till I figured it out.
