Whoa! 10 comets in a 10g tank!? Goldfish are one of the biggest waste produceing fish in the history of aquariums. They require at least 10 gallons...per fish, although many people say they should have more (and they should). How big are they? What kind of WC schedule do you have?
Also, comets are not suitable for the 10g aquarium. Many people believe this goldfish should be kept stricly as a pond fish, due to their love to dart all over the place (that is why they are called "commets").
I am not trying to scold anyone, I am just bringing it to the attention of the thread.
