Sunday October 13th, ammonia in tank nil, nitrites 0.25ppm and nitrates 180ppm.
I carried out an 80% water change, dropped the temperature to 23c and added 2ml of ammonia.

Monday October 14th, PH in tank 7.6, ammonia nil, nitrites nil, nitrates either 40 or 80 ppm (Difficult to be accurate as both similar on colour chart) I also tested the nitrates in my tap water which was 10ppm. (Last tested September 28th and it showed 5.0ppm

Does anyone have an idea why the nitrates are so high after an 80% water change ?

Geoff.

If your nitrates were 180ppm, then after an 80% water change you would expect them to be about 36ppm, (since 180x.2=36). Since you you are having trouble telling what your level is exactly due to the closeness of the colors, it may be reading 40ppm which is about where you'd expect it to be. Plus, nitrates may possibly been above 180 when you started if you couldn't tell the difference between colors too well.

I struggle with the test kit's due to my being colorblind.

If you want to get the nitrate lower, another water change would be in order.
