* some tadpoles eat some kinds of algae! You could leave the algae, and
see if the tadpoles seem to be nibbling on it - alternatively, maybe
there's plenty of food in your pond, and removing the algae is a way of
removing nutrients from the system (of course transforming frogs also
remove nutrients from the system).
