High so I have a 20 gallon high with 7 tiger barbs, 4 cories a albino BN pleco and a Golden wonder killi juvenile. Tiger barbs are going into a species 30 gallon. My nitrates are reading 20ppm and ph is between 6.5 and 7. All fish are healthy no signs of bad water quality or anything. Nitrate test bad and get a new one or is this possible
