What kind of filter (s) are you using.

what ever you do, dont take out all the grave all at once. dont want to shock your tank and start a mini cycle. gradually take it over the next week or so, so your filters can keep up.

This is the way to do it. Listen to the advice given by this guy. Just replace a bit at a time and then "be patient". Wait at least a week or so, before replacing more. Overall, if you are already stocked, you should take at least a month to entirely replace your substrate.
