It is better to use floating food for koi. And koi are hot herbivores.
They mostly need protein and fats supplied by the little critters that feed
on the algae. If the pond isnt big enough there wont be enough. Ingrid

Think I should use Koi food that sinks (if so, brand suggestion?) or
can I just not feed them and let them eat all that algae?
