Hi Matty, I am have the EXACT same issue as you, right down to the figures you mentioned. I also find it impossible to distinguish between the 40ppm and 80ppm colour. I had eye surgery a few years back and my colour vision in one eye was affected, so I put it down to that. Did you by any chance buy your test kit from Amazon.uk in the last year???. I'm thinking or hoping it's a bad batch and not my water. I tested bottled water, which said 11ppm on the label, my tap water and my tank water(just before my PWC). They all came out at between 40ppm and 80ppm. If you did buy from Amazon, we could compare lot numbers and see if they are the same or similar. I followed the instruction to the letter. I did notice something in the instructions though, maybe someone could clarify or explain it. It is in the Testing Tips paragraph, in the Nitrate Test section of the Instructions. I will quote it;Does anyone else have problems with the API nitrate test from the master test kit? My nitrate test always seems to be either 40ppm or 80ppm. Yes, I do bang the 2nd bottle well, give it a good shake. I ran a separate test using a Tetra liquid test and it seemed to show around 25ppm. Now I know that a lot of people agree API is one of the better test kits but I'm having this annoyance. I also tested my tap water and had the same readings. A thoughts on this or alternative tests for nitrates would be great. I the mean time I'm hoping my new water wisteria grows quickly and starts sucking some of that nitrate up.
I'm guessing your using Amazon.com, I use Amazon.UK. Here is it,If you could post your lot number I could compare mine as well. I bought mine off amazon this year so its possible. But I belive mine is correct due to my fish getting ill.
