not needed your system is perfectly capable of breaking it down with a cuc ( clean up crew) like crabs,worms,snails,urchns,pods ......you can leave the sponge but it would need to be rinsed very frequently or it ruins the risk of hosting ditrius and thus creating nitrates which in turn fuels yoiur algae
