    hello!
    guys my 30 gal goldfish tank filter is dying and not pumping that well
    just bought a 15 watt new filter for it today,i want to change the filters the old one media wont fit into the new one
    i read in internet that i can also put the old media next to the new filter so it will colonize the new filter
    my question is,since i have 2 big goldfish in this tank is it safe to just put the old media? since they create too much waste?
