Emergency Aeration for a Small, Smelly Yard Pond

Immediate Oxygen Boost

A 75–100 gallon pond with no pump cannot hold enough oxygen in summer. Fish gasping at the surface = critical hypoxia.

Today's Fix

1. Buy a submersible pump with fountain head (200–300 GPH) at any garden center.
2. Add an air stone on an aquarium pump as backup.
3. Do a 50% water change with dechlorinated water.
4. Remove excess sludge and decaying matter.

Ongoing Care

Run the pump 24/7. Add floating plants (water lettuce, hyacinth) for shade. Feed sparingly. Test ammonia weekly.
