My api and salifert nitrate tests are giving me very different results. API is showing close to 0 nitrates (no visible coloration whatsoever, solid yellow) and my salifert test is showing 25ppm. Neither test is expired (api is 4 years away from expiration date). Which would you trust? Salifert? Neither?
