Mature Media

nice simple question for you, will mature media from a filter used in a healthy coldwater tank be ok to use in a tropical set up ?

yep! are using the same gravel too? if not just get some of the old gravel in a cut off pair of tights and leave on the bottom of your new gravel to allow some bacteria to transfer

yeah im using the same sand thats in there just going to rake through it and give a 50% water change and let the water get upto temp before i move the fish over,

I dont see the point of going out of your way to include some of the old substrate, if you plan on using the same by all means do so. There is practically no bacteris in substrate and since you are using the same filter it would be bubkis... Im not sure about using the same media in hotter temp. water because the bacteria have to be sensitive to changes but as long as its not a HUGE difference you should be good.
