Aquarium Filter Priming?

Question

I want to know what exactly is priming(for basic external canister filters) for aquariums and how is it done....better if anyone can provide me with a detailed pictorial link to this.

Answer 1

I don't know what type you have, but all I have ever done is fill the filter with water and turn it on.

Priming simply means to have water when it starts.  This starts the siphoning.
