But of course, if you think the bio media is getting clogged with stuck-on organic matter, like bio film, then bleaching will indeed remove this. But as suggested above, do this to no more than 25% at a time, so each portion has a chance to re-grow the bacteria before you bleach the next lot. I would soak in bleach (diluted?) overnight, then rinse, then soak in dechlor overnight, then rinse. If it still smells of bleach, then another soak with new dechlor.
Do not use the newer 'splashless' or scented bleaches.
