Is there anyone here who lives in St. Paul? I want to know what kind of ferts to dose my planted tank with, but someone told me I should find out whats in the tap water I use first. Does anyone have any idea what the Nitrate, Phosphate or Potassium levels in the tap water are? I was told I should be able to find out if I call or find the website for the water district, but so far I've had no luck finding either the website or the phone number. I've tested for hardness and I get 8dGH, so I'm not too worried about the micronutrients. If anyone has any info it would be appreciated.
