Nitrate-N = 10 ppm means there is 10 ppm of N in the form of the nitrate ion (NO3-). The conversion factor from nitrate to nitrate-N is 4.43. In Canada, the limit for potable water is 10 ppm Nitrate-N, which is equivalent to 44.3 ppm nitrate (rounded to 45 ppm). Errors in reporting do happen and are serious.

The algal blooms that are common in newly set-up tanks are usually due to elevated nitrate levels. An algae bloom usually indicates high nitrate levels, though algae is able to grow in newly set-up tanks with nitrate levels as low as 10 ppm. Measuring Nitrate You will first need to determine what the nitrate level is in your aquarium by testing the tank water with a test kit. Nitrogen Standard, 1 mL = 0.01 mg N, 10 ppm N as Nitrate (44.27 ppm NO3-), Ricca Chemical Company Supplier: RICCA Chemical Company. R5456000-120A R5456000-500A. A nitrate reading of 10 ppm is OK for fish only. Corals will not last with it that high.
