My pool water is well balanced and very clear, but there is a greenish coating adhering to the floor and walls which cannot brush off. Could it be pollen?


The greenish coating is algae. You need to get rid of algae using Algaecide, which you can find on Amazon through a link in this article. If Algaecide does not work within 24 hours then you need to super shock the pool using plenty of liquid chlorine till the greenish coating disappear.
