With no plants, there is nothing to use either the light or the nutrients. And if I'm reading you correctly, and regular maintenance has been lacking, the nutrients will quickly overpower the system. Algae will use these in the presence of light. As I mentioned preivously, without plants, algae is a good thing; like plants, it uses nutrients and produces oxygen. However, there is a limit; this indicates deterioriating water quality which will be detrimental to the fish.
