Water is an “eager”
solvent for all manner of minerals, nutrients and foods.
water such as fountain water can become a veritable “soup” of dissolved and suspended materials. Such a “broth” is
quite attractive to algae, bacteria and fungi. Warmth, moisture, sunlight or darkness, nutrients and food - all
of the ingredients necessary for biological growth are present in a
fountain. The object of a biological
control program is to always make fountain water unattractive for biological
growth. The challenge is to inhibit
visible growth, not kill growth which has already occurred. Killing algae and slimes after they form is
a lost cause.
ask for much in life. They are simple plants which contain chlorophyll and are
usually green. They thrive on sunlight,
air, warmth and water “laced” with nutrients (fertilizers) - primarily nitrogen
and phosphorous. Bacteria and
fungi eat almost any organic material which finds its way into a fountain. They can live quite successfully on leaves,
pollens and dusts - even dead algae.
This means inhibiting algal growth is doubly important.
QUAT is a surface
active agent, a “surfactant” (detergent).
It reduces the ability of algae, bacteria and fungi to exclude outside
materials from entering the cell and interior materials from leaking out. The cell’s metabolism is disrupted and it
