Natural processes can cause low levels of nitrate in drinking water—usually less than 3 mg/L. The health concern is with levels of nitrate
over 10 mg/L
.
What happens if nitrate levels are too high?
If there is an excess level of nitrates, plants and algae will grow excessively. … An excess in the growth of plants and algae create
an unstable amount of dissolved oxygen
. During the day, there will be usually be high levels of dissolved oxygen, and at night the levels of oxygen can decrease dramatically.
What level of nitrates is too high?

20 to 50 ppm
are too high.
What is the ideal nitrate level in a fish tank?

below 20 mg/L
. However, any changes should occur slowly, only removing less than 50 mg/L of the Nitrate per day. Perform multiple small water changes.
How do I lower the nitrate levels in my fish tank?
