Nitrogen Cycle

he quality of your pond water directly affects the health of your plants and fish. Good water quality will result in healthy plants and fish where as poor water quality will do just the opposite. With proper Stocking, Filtration (if needed), Water Conditioning, and patience your pond will have good water quality. By these means, pond owners attempt to re-create what happens in nature so to achieve a balanced eco-system. This fundamental process is commonly known as the nitrogen cycle

THE NITROGEN CYCLE

STEP 1: Fish/scavengers waste, uneaten fish food, and plant matter are decomposed (eaten) by fungi and bacteria.
STEP 2: The fungi and bacteria release ammonia (which is toxic).
STEP 3: Ammonia is oxidized (eaten) by Nitrosomonas Bacteria.
STEP 4: Nitrosomonas Bacteria release nitrites (also toxic).
STEP 5: Nitrites are oxidized (eaten) by Nitrobacter Bacteria.
STEP 6: Nitrobacter Bacteria release nitrates (non-toxic plant food).
STEP 7: Plants absorb the nitrates as food.
STEP 8: Fish eat the plants, you feed the fish, plant matter dies, and the cycle starts over at step 1.

CHARACTERISTICS OF GOOD WATER QUALITY

  • Healthy plants and fish
  • Adequate oxygen levels
  • Low ammonia/nitrite levels

    CHARACTERISTICS OF POOR WATER QUALITY

  • Unhealthy plants and fish
  • Foul smell
  • Stagnation

    Note: Cloudy water is not necessarily a sign of poor water quality; nor is clear water necessarily a sign of good water quality. The best way to determine the quality of your water is to observe the fish/plants and to TEST it on a regular basis.
