What is considered high nitrates in a reef tank?

Although many aquarists run their tanks with extreme nitrate levels, the ideal is a maximum of 5 to 10 ppm. Levels of 20 to 50 ppm are too high. Freshwater tanks can be at the higher end, with marine fish-only setups at the lower end and reef tanks as near zero as possible.

How do you get nitrate levels down?

Will high nitrates kill plants?

If the level of nitrate in your system is above 150 parts per million (ppm), then the plant roots could get nutrient burn, which could be detrimental to their health. Additionally, having too much nitrate in the water is also toxic to the fish and can stress them out or even kill them over time.
