I haven't bought/used store bought filter media in over 10 years, mainly because most carbon is useless after about 2 weeks and I don't use it anyway...so why spent the money and when I did buy/use it I only changed it out maybe 1-2 times a year at most and only if it was falling apart...I now use poly fill a product from the craft department, one big bag cost about 5-6 bucks and last forever, I have 9 tanks and use filters on 4 of them, I cram the polyfill in my HBO's and leave it at that, I will give them a rinse in old tank water when the water flow slow down and that is about it......and due to keeping the natural planted soil based tanks I can toss the polyfill and replace with new and not worry about a mini-cycle....love my low tech tanks.....lol....
Get you old filter media and cut a slit in it and dump out the charcoal, give it a good rinse and put it back in the filter, you may have a mini-cycle so watch your water prams and make needed water changes...why spend money on something you don't need to...you want the filter media to look dirty...that is the good bacteria or food for the good bacteria, when the water flow slows, give it a swish in old tank water with a water change and your are good to go......
