What about snails or the catfish that are sold as algae eaters ?
========================
Both will eat leftover food the fish miss - neither eat mulm. Some snails
will nibble algae as well as consume your pond plants. Algae eaters eat
algae, not mulm. Some of these pet shop algae eaters will also attack fish
for their slime coats.

Nothing eats fish feces and rotten leaves and other debris on the pond
bottom. This dark smelly mulm is what the bacteria worked over and over.
You either remove it or it keeps collecting. Deadly gasses can start in a
deep layer of mulm and poison your whole pond.
