How often feed filter feeders?

Ok I have a coco worm and am looking at another fan worm in the future and was wondering how often I should feed phyto-feast and marine snow? Was feeding every other day

It says everyday 1 to 5 drops per gallon. Don't want to over feed tank. Looking for real world exp or can I really trust labels, got friends in advertising know the game
