High nitrate levels are often a sign of poorly maintained aquariums and will cause problems in the long term. Nitrate is either absorbed by aquatic plants or, in anaerobic conditions; it goes through the process of de-nitrification, which changes the nitrate back to nitrogen gas. Correct me if I am wrong but Ammonia is broken down by bacteria A which produces Nitrites, which are broken down by bacteria B, which produces Nitrates. NitrAte is part of the normal pond cycle. No such thing as good algae? It is a common question. After all we know our bio filters convert poisonous ammonia into poisonous nitrite and then into non poisonous nitrate.
