Hm I'm reading 10 mg/l (PPM) is the max in a human water supply. I'm in the UK. Why the heck is mine double this haha.

Its not double. The problem is the use of the word nitrate interchangeably with Nitrogen. The two words do NOT have the same meaning and yet get used interchangeably.

Your drinking water is required to have a measure of Nitrogen no more than 10ppm. That is measured by measuring the nitrates and doing the Math to covert it back to Nitrogen.

Roughly 45ppm of nitrate is equal to 10 ppm of nitrogen. Which means your tap water is 1/2 the standard, not double.

This website from the state of California does the best job of explaining the confusion I have seen, and even this is not really straight forward.

Cheers. Still tho, 20ppm nitrate in water sucks!
 
Steve R, I would get a RO system but i guess ur fish are use to nitrates.

The cleaner the water the better it is for fish, humans and cattle.
 
old thread guys. but 40 ppm of nitrate is beyond fine. u people aiming for 10 or below are on crack. no need for that. but to each his own. i aim for 50 ppm or less and my fish do great.

In my early years before i knew better i have kept fish in above 200 ppm and they were thriving. Heck most peacock eels never get larger than about 10" i grew my first one to 12" in those conditions.

dude, everything is linked to cancer. nice try though

Whilst I know why you say this, I take a different stance.

We know that generally self inflicted stuff does cause it.
Chain smoking, being very obese, eating a diet heavy in saturated fat with no vegetables, drinking toxic waste. There is merit to nitrate in drinking water increasing the incidence. Whilst I'll live my life, I'm not gonna deliberately do stuff already proven to cause cancer or increase the risk. Live fast and die young all you want, I don't want to be the 40yo in the cancer ward...I've seen it all too often. Unfortunately water is something we can't avoid though.
