  • Oxygen Depletion in Ponds
    Severe environmental stressors are the most frequent causes of sudden fish death in garden ponds or other fish habitats, and the lack of oxygen in the water is the number 1 stressor of all.

    Two major factors contributing to fish-pond oxygen loss concern blooming algae. During daylight hours, algae make oxygen; during the night, however, the plants take oxygen. If algae are profusely blooming, the plants deplete all the pond's oxygen during the night, which in turn, causes fish inhabiting the pond to die.

    Another way that algae trigger oxygen loss is by dying suddenly. Algae-bloom death occurs naturally or from chemical treatment of an algaecide. When algae die suddenly - from either cause - the oxygen becomes quickly depleted because the algae no longer are alive and making it.

    Then, when dead algae begin to decompose, the decaying process even further depletes oxygen. Fish have been observed gulping for oxygen at the water's surface in sixty minutes or less from the onset of sudden algae death.

    How to choose water garden plants
    So the water garden bug has bitten. You've dug and leveled and sweated and said words you hope that no one else has heard. Now it's time for the fun part - picking out your water garden plants!

    Plant varieties within these four categories are what you need to eyeball: deep-water, marginals, oxygenators, and floaters. (If you think these words are big words, just be happy we're not talking about medicine.)

    After you've diligently planted your new plants in plastic tubs, pans, or clay pots, packing the fertilizer- and chemical-free soil down tightly, load the container down with pea gravel to keep the soil from floating away. (Don't ask why this works, but it does.)

    Plunk your plant into the water at the appropriate depth (You'll read about that in just a minute) and you're on ready to go!
