red sea copper test kit

[dwint]

are these test kits accurate?i have had cuprisorb in my fishless tank for three days and no color change.ok that should mean im copper free but when i test it with this kit 0 should be green and to my eyes it is blueish.ive read reviews that the chart isnt to accurate so i was wondering if anyone has expierienced the same thing.i contacted seachem and said if i had copper it would of showed up blue by now.should i assume i am copper free?i want to buy fish soon but i dont need any copper in there

If thats what they told you at seachem then i would assume that your copper free, but if there's a small amount of copper it really won't have any effect on the fish because its so dilluted. But before you put any inverts in there I'd do a couple of water changes and maybe use some carbon in the filter to help further remove any excess.
