Hi, I live in Northern California, specifically city of Dublin in the tri-valley area.
I just got back into the hobby and trying EI dosing. I've noticed that my nitrates seems to always be really high no matter how much water I change out so I finally decided to test the tap water and I'm finding the nitrate test is showing maybe 5-10ppm of nitrates. Just to be sure my test kit is ok, I went out and bought some distilled water and tested that at the same time and it is showing 0 as expected.
So my question is, is it possible to have 5-10ppm nitrates in municipal tap water or could there be something else that's triggering a false positive?
And if there is nitrates in my water supply, for EI dosing, should I just dose k2so4 instead of kno3 to get potassium?
Here is a pic I took comparing the water.
I guess the next step is to calibrate my test kit using hoppys method and try and see exactly how much nitrates is in my water supply
