In the past my tanks have run between 5-10 ppm on Nitrates. Other bad stuff, zero. 25% water changes every week.
Because I feed my fish somewhat heavily I checked Nitrates. Maybe around 40 ppm. Other bad stuff zero.
So I checked my tap water; between 10-20 ppm (ground water, no Chloramines, just free Chlorine at about .8ppm).
Then I checked some bottled water (ozonated, R.O. treated) it showed about 5ppm.
I'm using an A.P.I. Pro kit. Closely following the directions.
Anyone else tested their tap water (or bottled water) for Nitrates and hit a positive?
