us: Pond Water Balance
1. Balance of plants to fish.
More plants and less fish mean less green water problems and cleaner water.
2. Balance of sun to shade.
More shade means less algae problems. However, less sum means less blooms on your water plants.
3. Balance of Nitrogen Cycle. (Simplified version)
Fish food à Fish waste à Decomposition by fungi and bacteria à Oxidation by more bacteria à nitrates and nitrogen (plant and algae food). Add some sunlight and algae and plants will thrive. Floating plants do double duty to help combat algae as they shade the water and use the nitrogen from the water.
4. Balance of plants to sunshine.
Plant coverage should be 60 to 80% of pond surface area. Water Lilly’s, hyacinths, water lettuce and parrot’s feather are excellent at shading the water surface.
5. With the exception of Lilly’s I recommend potting all water plants in soilless media as they will pull all their nutrients from the water. Lilly’s require soil and fertilizer in order to have good blooms they benefit from fertilizer tablets shoved just near the roots (to keep the fertilizer from the water use a heavy clay soil when planting them.
With proper filtration all the above rules can be broken!
1. The ultraviolet clarifier can correct all the green water problems when properly sized to the pond and pump.
2. The biological and mechanical filter can remove suspended particles and transform fish waste to usable food for your plants.
