reading seachem copper test colours

[magman53]

Hi All,

I am struggling to get a clear accurate reading on the seachem copper test (using seachem cupramine), I find the colour could easily be .25, or .5, anyone else have this problem to match the colour, even using the referance test, to me it could be.3 or .8

Besides that, confirm when you up at the dosage level, when you do a water change, you dose the new water at twice the dosage (2ml per 40ls), as the first two doses of 1ml per 40L are each to bring the dosage up to the desired .5.

I struggle reading the kit, and I have 20/20 colour vision, so I should be safe just using 2ml per 40L for any new water added.

Thanks in advance for any replies
