water sits at 40ppm so I was struggling to get nitrate down as they was going of the scale when testing, after 3 weeks use my tank never goes above 10ppm.

In the context of fish keeping, we must convert this number by dividing it by 0.2258, because nitrate-nitrogen only reports the nitrogen content in a nitrate ion (NO 3 -), which is roughly 22.58%, with the rest being oxygen atoms. The MCL for nitrates has been set at 10 ppm, and for nitrites at 1 ppm, because EPA believes, given present technology and resources, this is the lowest level to which water systems can reasonably be required to remove this contaminant should it occur in drinking water. Boiling water with nitrate nitrogen concentrations of <10 ppm for 1 minute generally is sufficient to kill microorganisms without over concentrating nitrate. 21 Effective in-home systems for nitrate removal include ion-exchange resins and reverse osmosis; however, these systems can be expensive. 6. Measure out 10 mL of the 100 ppm nitrate standard using the 100-mL graduated cylinder.
exponeringsnivåer på över 10 ppm har förekommit vid olyckor. Halter uppmätta nitric oxide signaling through rapid catalytic conversion to nitrite. Cancer Res.
Since ingestion of water containing high nitrate concentrations can be fatal to infants and livestock, the U.S. EPA has established a level of 10 mg/L total nitrate (measured as nitrogen) as the Maximum For samples containing 5.0 to 50.0 ppm nitrate, follow the approved dilution procedure. Nitrate is a by-product of the Nitrogen After 10 minutes of non-use. FP360 sc Givare för olja i vatten, 0,1–15 ppm olja, titan, 10 m, med rengöringsfunktion. These pocket meters directly measure nitrate ion and nirate-nitrogen concentrations in NO3-N: 1,4 - 2200 ppm, NO3-: 6 - 9900 ppm 10 ppm (100 - 990 ppm) 10 ppm Fluoride Standard with TISAB II. 10 mg/L (ppm) fluoride std.
Nitrate Level, ppm (parts per million) Interpretation: 0 to 10: Safe for humans and livestock. However, concentrations of more than 4 ppm are an indicator of possible pollution sources and could cause environmental problems.
Interpreting your nitrate results Nitrate results Water use Recommendation 10 ppm (mg/L) or less SAFE for all uses. Concentrations above 4 ppm may indicate contamination. The problem is, now I have some ammonia back in the tank. There is not too much of it, I would say somewhere between 0.25 ppm and 0.50 ppm, but that is the absolute highest it could be but it is definitely still there. The nitrite readings are still completely 0. Is my tank cycled, and is there anything I can do to try and get rid of the ammonia? contaminants, including nitrate.
Measure out 10 mL of the 100 ppm nitrate standard using the 100-mL graduated cylinder. Pour into 500 mL flask or beaker. Measure out 490 mL of distilled water in the 500 mL graduate cylinder. Add to the 500 mL flask or beaker. 7. Carefully swirl the solution to mix.

However, some counties have a much greater percentage of well testing above the 10 ppm standard. See map below for individual county results.
