A light ballast is something that is necessary to make a fluorescent light work. They wear out and need to be replaced. Some are easier than others to replace. Most parts are available at big box hardware stores.
As for 404, I cant help there. I would most definately recommend a new set of gaskets though before you use it. I have a 406 and I am very happy
No, it is not hard to put together, but it does take at leadt an hour to do. Only scary part is cutting the hose. Make sure you know where you want to place your cannister, intake and outflow before you cut anything.
You can view the installation instructions online before you purchase and judge for yourself.
hey guys, I have the chance to buy a used Fluval 404 for next to nothing. Apparently in very good condition.
How his your experience with that one?
