FishLab Fact:The“lower nitrates are better”rule is thrown out the window if you have a planted aquarium. Many plants use nitrates for food, and in this case, low nitrate levels can actually cause problems and can even lead to ablue-green algae(cyanobacteria) outbreak. ...
Further Reading: Bio Load in Aquarium or PondStudies show that the toxicity of nitrate is due to nitrite being an intermediate. Nitrites oxidize the iron atoms in hemoglobin from ferrous iron (2+) to ferric iron (3+), rendering it unable to carry oxygen. This process can lead to generali...
