The freezing temperatures must be unpleasant for the fish, at best. Add to that the decreased oxygen and increased toxins due to decaying leaves, and fish may send signals your way, far worse than just a dirty look .
A little help is all they need. Leave it to the tiniest organisms to do the biggest jobs.
Beneficial bacteria can be added to the water to jump start the natural process of organic matter decay. Bacteria possess a wide range of capabilities, including eating the leaves and debris in ponds. In the process, they increase available oxygen and beneficial enzymes in the water, much to the delight of the fish. Barley straw naturally produces these helpful enzymes, as it decays. Extracts of barley straw can also be added for a similar effect to the water.
