What buyers praise, what they complain about and why they send it back, from the reviews.
Complain
Do not work
The nitrate number 3 doesnt work
Ammonia test doesn't work at all
They never change colour
If you hold it too close to the chart it darkens the colour of your sample
now no readings on half the colour chart
Buy Cheap Buy Twice
Rubbish
that simply is not good enough
The advertising is misleading
Does not test for ammonia as stated in description and picture
The test strips dont come close to the results you can get from liquid tests
would indicate either inconsistent filing of the bottles or drop sizes from the dropper
In UK it is routinely added to the water supply, its unavoidable and these strips are definitely not picking this chemical up at levels which would be unsuitable for fish
