I'm very lucky with my tap water here in Lincolnshire it always reads 0 ppm on API test kit.Nice write up Andy as always. I aquired my dovii at about 60mm long June last year ibelieve, I'm now eyeballing him at 9.5 inch so I'm guessing I'm about on par at 6inch per year here, that's in crappy Kent UK tap water 30+ppm nitrate before it hits the tank!
