Just wondering if I can reuse 2nd hand filter media or if I should buy new? Am upgrading my fluval 307 to a 407 which I’ve purchased 2nd hand. I am planning to put all my existing basket media into the new filter but what about the bio foam/bio foam max sponges that sit vertical in the filter - my current ones are too small to go in the 407 so can I use their existing ones that came with it (once cleaned & rinsed in my old tank water) or should I just purchase new ones?
