High nitrate from tap???
So the best way to remove nitrate is to do a water change, but what if I have high nitrate in my tap? With my API test kit it looks like I have 10-20 ppm out of my tap. We also have hard water. Would it ok to use distilled water mixed with my tap when I do a water change? I figure if I do a 50/50 mix it will cut the nitrate's in half and keep the minerals from getting out of control.
