I have a 10gal Freshwater Tank approximately one month old which is exhibiting high levels of both Nitrates and Nitrites. I understand that the former is not necessarily detrimental to the health of the Fish, but the latter is.

This is a simple setup with four Goldfish, a Marineland C160 Filter, heater, a few sandstones, etc. The setup is in a room that receives a large amount of light, which is no doubt contributing to the Algae problem mentioned below.

Is there any way I can get these levels down?

Also, I have now run into an Algae problem. What is the best way to deal with this? I would assume this will include a substantial tank change and to that end I assume the contents of the filter should likewise be drained?

Thanks!
