buy an algae eater!

Answer 2

remember that the Miss Peach really does not need that much food so go easy on the food.  the leftover food along with the waste that sinks to the bottom will eventually create its own ecosystem so you really do not want to clean all at once.  it is just like a reg fish tank so never change all the water at once.  you don't want to shock Miss Peach.  the sell little gravel cleaners that will suck up a little of the "stuff" at the bottom while not disturbing the whole tank.  it is a tube looking things with a catch thing at the bottom.  just ask the person in the fish department if they have gravel cleaners.  it should be about 8 bucks or so.  good luck and Miss Peach will be happy you did not destroy her ecosystem.
