1.  Should I worry about nitrate?

Although nitrate does not represent a direct health threat to most fish, high levels are still undesirable. Apart from encouraging unsightly algal growth, it is now believed that high nitrate levels are implicated in some fish diseases. In nature the fate of most nitrate would be assimilation by plants to produce organic nitrogen compounds as part of the nitrogen cycle. Nitrates are removed from the aquarium by regular water changes
