Still in the clear, Ammonia is also zero, PH is 7.4, NO2 is Zero, and NO3 is either 10 or 20ppm, the trouble is the colour checker basically shows the same colour for both of these.

Did an NO2 test again this morning, it was reading 0.25ppm kind of violet colour, I can't help but think it's something to do with that very fine white section of the filter which I had to add back into the filter last night as per Dr Tim's bottle instructions, I'll check it again when I get home and probably do a water change anyway.
