I have filled my new tank with water processed through a HMA filter and have offered to supply a work colleague with the same. As he lives some distance away he tested my water for nitrate as his comes out of the tap at 20ppm. I gave him both tap and filtered water to test and my tap water comes out at 5ppm but the filtered comes out at 20ppm. I have now run the same tests and both results were the same as his.
I am going to fishless cycle, but wondered why nitrate is higher after HMA filtration?
Hoping someone has an answer.
